factor 21x^2-29xy-72y^2

factor

21 x^{2} - 29 x y - 72 y^{2}

(7 x + 9 y) (3 x - 8 y)

Solution steps

21 x^{2} - 29 x y - 72 y^{2}

Break the expression into groups

= (21 x^{2} + 27 x y) + (- 56 x y - 72 y^{2})

Factor out

3 x

from

21 x^{2} + 27 x y : 3 x (7 x + 9 y)

Factor out

- 8 y

from

- 56 x y - 72 y^{2} : - 8 y (7 x + 9 y)

= 3 x (7 x + 9 y) - 8 y (7 x + 9 y)

Factor out common term

7 x + 9 y

= (7 x + 9 y) (3 x - 8 y)

- 16 t^{2} + 192 t = 0

19 6^{\frac{1}{2}}

(1 + i) (1 + i)

12 x^{3} + 2 x^{2} - 30 x - 5

\frac{6 x}{x - 1} \leq \frac{x}{x + 3} + 6
