factor x^2-3xy-4y^2

factor

x^{2} - 3 x y - 4 y^{2}

(x + y) (x - 4 y)

Solution steps

x^{2} - 3 x y - 4 y^{2}

Break the expression into groups

= (x^{2} + x y) + (- 4 x y - 4 y^{2})

Factor out

x

from

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

Factor out

- 4 y

from

- 4 x y - 4 y^{2} : - 4 y (x + y)

= x (x + y) - 4 y (x + y)

Factor out common term

x + y

= (x + y) (x - 4 y)

\frac{15 ( x - 3 )}{5} = 3 (2 x - 3)

- 2 u + 8 u = - 15

\frac{( x + 1 )}{x} \geq 0

\frac{d}{5} = - 7

x^{2} - 15 x - 16
