factor x^2-21x+20

factor

x^{2} - 21 x + 20

(x - 1) (x - 20)

Solution steps

x^{2} - 21 x + 20

Break the expression into groups

= (x^{2} - x) + (- 20 x + 20)

Factor out

x

from

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

Factor out

- 20

from

- 20 x + 20 : - 20 (x - 1)

= x (x - 1) - 20 (x - 1)

Factor out common term

x - 1

= (x - 1) (x - 20)

3 x + 1 = 7

6 - ∣ 2 x - 2 ∣ \geq 1

x > \frac{- 1}{8}

(\frac{( 4 x ^{2} y ^{3} ) ^{0}}{- 3 x ^{- 1} y ^{2}})^{3}

- 4 x + 3 = - 11
