Question

plz give me this answer
​

Answer 1

Step-by-step explanation:

x^2- 8x - 2x + 16

= x( x-8) -2(x -8)

= (x-2)(x-8)

x = 2 , 8

Answer 2

$\Large{\bf{\green{\mathfrak{\dag{\underline{\underline{Given:-}}}}}}}$

• x² - 10x + 16

$\Large{\bf{\orange{\mathfrak{\dag{\underline{\underline{To \: Find:-}}}}}}}$

• Roots

$\Large{\bf{\red{\mathfrak{\dag{\underline{\underline{Solution:-}}}}}}}$

• x² - 10x + 16

We will be using PSF method to find the roots,

• P = 16 * x² = 16x²

• S = - 10x

• F = - 8x , - 2x

Substituting the factors in place of - 10x,

• x² - 10x + 16

• x² - 8x - 2x + 16

• x (x - 8) - 2 (x - 8)

• (x - 8)(x - 2)

Equating with 0,

• (x - 8)(x - 2) = 0

• x - 8 = 0 , x - 2 = 0

• x = 8 , x = 2

• x = 8, 2

Therefore,

• Roots of x² - 10x + 16 are 8 and 2.
