Answer 1

Answer:

-x2+8x+2x-16

-x(X+8) -2(x+8)

X=8,-2

Hope u got it mark me brainliest

Answer 2

EXPLANATION.

Equation :

⇒ 10x - x² = 16.

As we know that,

We can write equation as,

⇒ 16 + x² - 10x = 0.

⇒ x² - 10x + 16 = 0.

Factorizes the equation into middle term splits, we get.

⇒ x² - 8x - 2x + 16 = 0.

⇒ x(x - 8) - 2(x - 8) = 0.

⇒ (x - 2)(x - 8) = 0.

⇒ x = 2  and  x = 8.

                                                                                                                     

MORE INFORMATION.

Conjugate roots.

D = Discriminant Or b² - 4ac.

(1) If D < 0.

One roots = α + iβ.

Other roots = α - iβ.

(2) If D > 0.

One roots = α + √β.

Other roots = α - √β.
