factor x^2-10xy+21y^2

factor

x^{2} - 10 x y + 21 y^{2}

(x - 3 y) (x - 7 y)

Solution steps

x^{2} - 10 x y + 21 y^{2}

Break the expression into groups

= (x^{2} - 3 x y) + (- 7 x y + 21 y^{2})

Factor out

x

from

x^{2} - 3 x y : x (x - 3 y)

Factor out

- 7 y

from

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

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

Factor out common term

x - 3 y

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

112 b^{3} + 34 b^{2} - 6 b

4 x + 8 < 4 + 6 x

x^{2} - 4 x = 11

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

\frac{1}{2} + \frac{1}{5}
