Question

X squared + 12 x + 3 = 7 solve by completing the square

Answer 1

1/6?

Explanation:

Answer 2

ax^2 + bx + c

x^2 + 12x + 3 = 7

x^2 + 12x = 4

Take b, half it, then square it--

x^2 + 12x + 36 = 40

That equation becomes

(x+6)^2 = 40

+ 6 = ± (square root of 40)

= 0.324555

= −12.3246
