factor 4m^2-4m-63

factor

4 m^{2} - 4 m - 63

(2 m + 7) (2 m - 9)

Solution steps

4 m^{2} - 4 m - 63

Break the expression into groups

= (4 m^{2} + 14 m) + (- 18 m - 63)

Factor out

2 m

from

4 m^{2} + 14 m : 2 m (2 m + 7)

Factor out

- 9

from

- 18 m - 63 : - 9 (2 m + 7)

= 2 m (2 m + 7) - 9 (2 m + 7)

Factor out common term

2 m + 7

= (2 m + 7) (2 m - 9)

∣ 5 x - 7 ∣ + 7 = 6

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

∣ p + 4 ∣ \leq 8

\frac{\frac{1}{2}}{4}

y, 2 x^{2} + 2 y^{2} - 2 x + 6 y + 5 = 0
