factor 90m^2-19m-90

factor

90 m^{2} - 19 m - 90

(10 m + 9) (9 m - 10)

Solution steps

90 m^{2} - 19 m - 90

Break the expression into groups

= (90 m^{2} + 81 m) + (- 100 m - 90)

Factor out

9 m

from

90 m^{2} + 81 m : 9 m (10 m + 9)

Factor out

- 10

from

- 100 m - 90 : - 10 (10 m + 9)

= 9 m (10 m + 9) - 10 (10 m + 9)

Factor out common term

10 m + 9

= (10 m + 9) (9 m - 10)

\frac{( 1 + i )}{1 - i}

y - 17 = 11

\frac{x ^{2} + 10 x + 16}{x - 3} > 0

2 ab - 3 b + 4 a - 6

2 - \frac{2}{3} x \geq 0
