factor x^2-16x+15

factor

x^{2} - 16 x + 15

(x - 1) (x - 15)

Solution steps

x^{2} - 16 x + 15

Break the expression into groups

= (x^{2} - x) + (- 15 x + 15)

Factor out

x

from

x^{2} - x : x (x - 1)

Factor out

- 15

from

- 15 x + 15 : - 15 (x - 1)

= x (x - 1) - 15 (x - 1)

Factor out common term

x - 1

= (x - 1) (x - 15)

2 x^{2} + x \geq 1

(3 z - 2)^{2} = 4

(4 a)^{2}

x^{2} + 13 x - 12 = 0

5 s^{2} = 11 s + 12
