factor 64x^2+32xy-21y^2

factor

64 x^{2} + 32 x y - 21 y^{2}

(8 x - 3 y) (8 x + 7 y)

Solution steps

64 x^{2} + 32 x y - 21 y^{2}

Break the expression into groups

= (64 x^{2} - 24 x y) + (56 x y - 21 y^{2})

Factor out

8 x

from

64 x^{2} - 24 x y : 8 x (8 x - 3 y)

Factor out

7 y

from

56 x y - 21 y^{2} : 7 y (8 x - 3 y)

= 8 x (8 x - 3 y) + 7 y (8 x - 3 y)

Factor out common term

8 x - 3 y

= (8 x - 3 y) (8 x + 7 y)

12!

\frac{7 ^{11}}{4 ^{11}}

\frac{x}{4} - \frac{1}{2} \leq \frac{x}{2} + 1

64 - 9 x^{2}

k^{2} - 6 k + 9
