factor 12a^2b+8by-21a^2c-14cy

factor

12 a^{2} b + 8 b y - 21 a^{2} c - 14 cy

(3 a^{2} + 2 y) (4 b - 7 c)

Solution steps

12 a^{2} b + 8 b y - 21 a^{2} c - 14 cy

Factor

12 a^{2} b + 8 b y : 4 b (3 a^{2} + 2 y)

Factor

- 21 a^{2} c - 14 cy : - 7 c (3 a^{2} + 2 y)

= 4 b (3 a^{2} + 2 y) - 7 c (3 a^{2} + 2 y)

Factor out common term

(a^{2} \cdot 3 + 2 y)

= (a^{2} \cdot 3 + 2 y) (4 b - 7 c)

(- 4) 3 \cdot (- 2)^{- 3}

cos^{2} (x) - 2 cos (x) - 3

(x - 2) (2 x + 1)

(x + y)^{2} - 10 (x + y) - 24

6 + 10
