factor 12b^2+11b-15

factor

12 b^{2} + 11 b - 15

(4 b - 3) (3 b + 5)

Solution steps

12 b^{2} + 11 b - 15

Break the expression into groups

= (12 b^{2} - 9 b) + (20 b - 15)

Factor out

3 b

from

12 b^{2} - 9 b : 3 b (4 b - 3)

Factor out

5

from

20 b - 15 : 5 (4 b - 3)

= 3 b (4 b - 3) + 5 (4 b - 3)

Factor out common term

4 b - 3

= (4 b - 3) (3 b + 5)

4 x^{2} + 12 x + 9

(- 2)^{4} > 2^{4}

- 3 < x + 20 < 5

9 (c + 2) - (c + 2)^{2}

- 6 y^{2} - 9 y = - 1
