factor x^2+10xy-39y^2

factor

x^{2} + 10 x y - 39 y^{2}

(x - 3 y) (x + 13 y)

Solution steps

x^{2} + 10 x y - 39 y^{2}

Break the expression into groups

= (x^{2} - 3 x y) + (13 x y - 39 y^{2})

Factor out

x

from

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

Factor out

13 y

from

13 x y - 39 y^{2} : 13 y (x - 3 y)

= x (x - 3 y) + 13 y (x - 3 y)

Factor out common term

x - 3 y

= (x - 3 y) (x + 13 y)

x^{3} - x^{2} \leq 0

\frac{( - 3 ) ^{2} + 4}{( - 3 )}

∣ x + 7 ∣ < 7

18 (x + y) + 9 z (x + y) + z^{2} (x + y)

(\frac{- 2}{5})^{2}
