Advertisement Answer 5.0 /5 42 amna04352 Answer: TikTok video from Chase Lee (@chaseleee): " x equals negative b plus or minus the square root of b squared minus 4ac all over 2a #fyp #foru #stemlife #myhobby". The APPLY element is used as a container for the operator and its operands. Step-by-step explanation: In this case, a is 1, b is 4 and c is 4. Answer (1 of 3): This is called the "quadratic formula" and is used to solve any quadratic equation, which is an equation of the form ax^2 + bx +c = 0 For example, 3x^2+x-2=0 In this case, a=3, b=1, and c=-2. It is read "x equals the opposite of b, plus or minus the square root of the quantity b squared minus 4ac, all divided by 2a." To use the quadratic formula to solve an equation, you will substitute the values of a, b, and c into the quadratic formula. Quadratic Formula: x = b (b2 4ac)2a. C: The square root of terms separated by addition and subtraction cannot be calculated individually. If it's positive, parabola has 2 real solutions. b 2-4ac=0 if one distinct root. answer=5 plus or minus the square root of 37 over 6 2)Use the discriminant to determine the number and type of roots for the equation 2x^2-7x+9=0 answer=2 . Solve for b x= (-b+ square root of b^2-4ac)/ (2a) x = b + b2 4ac 2a x = - b + b 2 - 4 a c 2 a. Rewrite the equation as b+b2 4ac 2a = x - b + b 2 - 4 a c 2 a = x. And then plus or minus-- and what's important point about this guy? x = -2. The derivation is complete. A little different from the natural frequency. B: The symbol prevents the square root from being evaluated. plus or minus the square root, b-squared minus 4ac, divided by 2a. Two real distinct solutions. b+b2 4ac 2a = x - b + b 2 - 4 a c 2 a = x. Simplify both sides of the equation. A: Negative values, like 4ac, do not have a square root. By substituting in given values for the variables a, b, and c, you can solve for x using the quadratic formula. 1 Flag Get the Quadratic Formula mug. The E element is used in place of APPLY for relational operators such as equals, which is represented as <EQ/> . TikTok video from julia<3 (@juliaa.natalia): "negative b plus or minus the sqaure root of b squared take four a c all over two a #gcses2022 #furthermaths". "b" plus or minus the square root of "b" squared minus 4. This online calculator is a quadratic equation solver that will solve a second-order polynomial equation such as ax 2 + bx + c = 0 for x, where a 0, using the quadratic formula. The means there are TWO answers: x = b + (b 2 4ac) 2a. Other people claimed to have learned the handy formula by singing it to the tune of: Frre Jacques 5 for b in the expression. Reminder, the square root of a number results in plus or minus the result. Step 6: The equation on the left is to be written as a perfect square as shown (x+b/2a) = (-4ac+ b)/4a. The symbol prevents the square root from being evaluated. The two solutions to x 2 Lawrence C. Rifki Ridha x equals negative b plus or minus the square root of b take away 4ac all over 2a So the plus or minus, there's an imaginary number. plus or minus the square root of Becky squared minus 4 Ann-Cody, over 2 Anns." 2. We will get this solution set if \({b^2} - 4ac > 0\). Plus/Minus. . x + b/2a . Expert Answer. Summary. "Negative b plus or minus the square root of b squared minus 4ac all over 2a." . Step 7: Take the square root of both sides The entire term b2 4ac must be divided by 2a before its square root can be determined.
