Question

Factor the Quadratic Equation. 62° - 72 - 20Use factor by GroupingA. (22+5) (3x - 4)B. (2x - 5)(3x + 4)C. (5x - 2) (3x + 4)D. (2x - 5) (4x + 3)

Answer 1

we have

6x^2 -7x -20

Find the zeros of the equation

Complete the square

Factor 6

6(x^2-7/6x)=20

6(x^2-7/6x+49/144)=20+49/24

rewrite as perfect squares

6(x-7/12)^2=529/24

square root both sides

-7/6x+49/144
