Question

Which shows the equation below written in the form ax2 + bx + c = 0?

Answer 1

Answer:

D

Step-by-step explanation:

We have the equation:

$x+9=4(x-1)^2$

To convert this to standard form, we can simply expand.

First, expand the right-hand side:

$x+9=4(x^2-2x+1)$

Distribute the right:

$x+9=4x^2-8x+4$

Subtract 9 from both sides:

$x=4x^2-8x-5$

Finally, subtract an x from both sides:

$0=4x^2-9x-5$

Flip:

$4x^2-9x-5=0$

Hence, our answer is D.
