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

x + 10 = 3 (x - 1) ^2

A. 3x2 - 5x + 13 = 0

B. 3x2 - 7x + 13 = 0

c. 3x2-77-7 = 0

D. 3x2 - 5x - 7 = 0

3x² - 7x - 7 = 0

Step-by-step explanation:

Given

x + 10 = 3 (x - 1) ² ← expand the factor

x + 10 = 3 (x² - 2x + 1) ← distribute by 3

x + 10 = 3x² - 6x + 3 (subtract x + 10 from both sides)

0 = 3x² - 7x - 7 or

3x² - 7x - 7 = 0

C

Step-by-step explanation:

x+10＝3 (x2-2x+1)

x+10＝3x2-6x+3

3x2-7x-7＝0
