factor 21x^2-22xy+5y^2

factor

21 x^{2} - 22 x y + 5 y^{2}

(3 x - y) (7 x - 5 y)

Solution steps

21 x^{2} - 22 x y + 5 y^{2}

Break the expression into groups

= (21 x^{2} - 7 x y) + (- 15 x y + 5 y^{2})

Factor out

7 x

from

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

Factor out

- 5 y

from

- 15 x y + 5 y^{2} : - 5 y (3 x - y)

= 7 x (3 x - y) - 5 y (3 x - y)

Factor out common term

3 x - y

= (3 x - y) (7 x - 5 y)

\frac{3 z}{2} + \frac{1}{4} = \frac{7}{8}

8 x^{2} - 38 x + 9

- 3 + 13

\frac{4}{n - 4} - \frac{6}{3 n ^{4} + 6 n ^{3}}

8 x + 3 (2 - x) = 5 x + 6
