factor 4m^2+4m-15

factor

4 m^{2} + 4 m - 15

(2 m - 3) (2 m + 5)

Solution steps

4 m^{2} + 4 m - 15

Break the expression into groups

= (4 m^{2} - 6 m) + (10 m - 15)

Factor out

2 m

from

4 m^{2} - 6 m : 2 m (2 m - 3)

Factor out

5

from

10 m - 15 : 5 (2 m - 3)

= 2 m (2 m - 3) + 5 (2 m - 3)

Factor out common term

2 m - 3

= (2 m - 3) (2 m + 5)

8 (2 x - 6) = 96

f = (- 2)^{3}

4 x^{2} - 5 x + 9 = 0

- 8 \leq z - 15 \leq - 3

2 = 10 c - 4 (2 c - 9)
