Question

Patel is solving 8x2 + 16x + 3 = 0. Which steps could he use to solve the quadratic equation? Check all that apply. 8(x2 + 2x + 1) = –3 + 8 x = –1 x = –1 8(x2 + 2x + 1) = 3 + 1 8(x2 + 2x) = –3

Answer 1

Answer:

Patel can use the first and last steps.

Step-by-step explanation:

The given equation is :

$8x^{2} +16x+3=0$

Patel can use the last step.

$8(x^{2} +2x)+3=0$

Taking 3 to right hand side, we get

$8(x^{2} +2x)=-3$

He can also use this step.....

$8(x^{2} +2x+1)=-3+8$

Upon solving we get,

$8x^{2} +16x+8=-3+8$

=> $8x^{2} +16x=-3+8-8$

=> $8x^{2} +16x=-3$
