x^2-2x+8=(x+4)(x-2)

x^{2} - 2 x + 8 = (x + 4) (x - 2)

x = 4

Solution steps

x^{2} - 2 x + 8 = (x + 4) (x - 2)

Expand

(x + 4) (x - 2) : x^{2} + 2 x - 8

x^{2} - 2 x + 8 = x^{2} + 2 x - 8

Move

8

to the right side

x^{2} - 2 x = x^{2} + 2 x - 16

Subtract

x^{2} + 2 x

from both sides

x^{2} - 2 x - (x^{2} + 2 x) = x^{2} + 2 x - 16 - (x^{2} + 2 x)

Simplify

- 4 x = - 16

Divide both sides by

- 4

x = 4

x - 47 = - 25

y = ∣ - 2 ∣

x, x - 3 y = 18 x

6 (4 m - 3) + 6 = 4 (4 m + 11)

4 x + 5 = 3 x + 9
