factor x^2-xy-2y^2

factor

x^{2} - x y - 2 y^{2}

(x + y) (x - 2 y)

Solution steps

x^{2} - x y - 2 y^{2}

Break the expression into groups

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

Factor out

x

from

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

Factor out

- 2 y

from

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

= x (x + y) - 2 y (x + y)

Factor out common term

x + y

= (x + y) (x - 2 y)

16 t^{7} + 250 t^{4}

7 + 3 x > 2 x - 5

x \cdot 3 = 4

(\frac{x}{y})^{- 2}

36 x^{2} - y^{2}
