Question

?Write the equation in standard form. Then factor the left side of the equation.? 2x2 = 28 – x A.) (2x + 7)(x – 4) = 0 B.) (2x – 7)(x + 4) = 0 C.) (2x + 4)(x + 7) = 0 D.) (2x – 4)(x + 7) = 0

Answer 1

2x² = 28 - x

2x²+x-28=0

2x²+8x-7x-28=0

2x(x+4)-7(x+4)=0

(x+4)(2x-7)=0

(2x-7)(x+4)=0

B.) (2x - 7)(x + 4) = 0
