factor a^2-9ab+20b^2

factor

a^{2} - 9 ab + 20 b^{2}

(a - 4 b) (a - 5 b)

Solution steps

a^{2} - 9 ab + 20 b^{2}

Break the expression into groups

= (a^{2} - 4 ab) + (- 5 ab + 20 b^{2})

Factor out

a

from

a^{2} - 4 ab : a (a - 4 b)

Factor out

- 5 b

from

- 5 ab + 20 b^{2} : - 5 b (a - 4 b)

= a (a - 4 b) - 5 b (a - 4 b)

Factor out common term

a - 4 b

= (a - 4 b) (a - 5 b)

(8 - 2 x) (2 + 3 x) \geq 0

(4^{5})^{7}

\frac{8 c ^{6}}{5 c}

2 x > - 10 and 9 x < 18

- 4 < \frac{2 - 5 x}{3} \leq 2
