To complete the square we get the coefficient of x, divide it by 2 then square it.
-3/4 divided by 2 =
-3/8 and then squared it equals

What the answer to this problem I need the answer as soon as possible

DENIUS [597]

I am not that sure but I believe it would be 12 and 1/2 points since that would have brought him back up to 100%. Because if it was any other it would make his score lower than 100% or higher then 100%

What equation results from completing the square and then factoring? x2 + 10X = 15

Mandarinka [93]

Answer:

C) (x + 5)² = 40

Step-by-step explanation:

Given the quadratic equation, x² + 10x = 15:

To complete the square, take the coefficient of the middle term (b), and divide it by 2a:

x² + 10x + $[\frac{b}{2a}]^{2}$ = 15 + $[\frac{b}{2a}]^{2}$

x² + 10x + $[\frac{10}{2}]^{2}$ = 15 + $[\frac{10}{2}]^{2}$

x² + 10x + 5² = 15 + 5²

x² + 10x + 25 = 40

The trinomial on the left-hand side of the equation provides a perfect square binomial factors: u² + 2uv + v² = (u + v)²

x² + 10x + 25 = 40

(x + 5)² = 40

Therefore, the correct answer is Option C) (x + 5)² = 40
