factor x^2-4xy-77y^2

factor

x^{2} - 4 x y - 77 y^{2}

(x + 7 y) (x - 11 y)

Solution steps

x^{2} - 4 x y - 77 y^{2}

Break the expression into groups

= (x^{2} + 7 x y) + (- 11 x y - 77 y^{2})

Factor out

x

from

x^{2} + 7 x y : x (x + 7 y)

Factor out

- 11 y

from

- 11 x y - 77 y^{2} : - 11 y (x + 7 y)

= x (x + 7 y) - 11 y (x + 7 y)

Factor out common term

x + 7 y

= (x + 7 y) (x - 11 y)

\frac{16 m ^{4} - 81 n ^{4}}{2 m - 3 n}

\frac{1}{2} + \frac{3}{2} + 6 - 3

2 k^{2} - 16 k - 40

4 x > 8

7 y^{2} + 15 y + 2
