B Getting to the Answer: Set the equation equal to zere, then divide through by 3 on both sides to remove the -coefficient: 3x^2+9x-54=0 x^2+3x-18=0 (x-3)(x+6)=0 x=30r-6 The question asks for the sum of the roots, which is 3t(t)=3. The correct answer is (B)....
The roots of this equation are −8 and 8 and product is −8×8=(A) −64. Square both sides, to get 5|x|+8=x2−16. Rearrange to get x2−5|x|−24=0. Seeing that x2=|x|2, substitute to get |x|2−5|x|−24=0. We see that this is a quadratic in |x...

What are the roots of the quadratic equation x^{2}+7x+6=0. What are the roots of the quadratic equation 2x^2 - 12x + 13 = 0? What are the solutions of the quadratic equation below? 4x^2 - 9x - 9 = 0 What are the solutions to the quadratic equation 4x^2 = 64?
A root is where the function crosses the x-axis. In terms of numbers, it's where y or f(x) is equal to 0. To find the roots of a given function, put 0 in for f(x) and solve for x using the method that you prefer.
