factor x^2+2ax-15a^2

factor

x^{2} + 2 a x - 15 a^{2}

(x - 3 a) (x + 5 a)

Solution steps

x^{2} + 2 a x - 15 a^{2}

Break the expression into groups

= (x^{2} - 3 x a) + (5 x a - 15 a^{2})

Factor out

x

from

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

Factor out

5 a

from

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

= x (x - 3 a) + 5 a (x - 3 a)

Factor out common term

x - 3 a

= (x - 3 a) (x + 5 a)

\frac{3 k}{3 k - 6} - \frac{2 k}{k + 3}

\frac{0. 9 ^{4} - 1}{0. 9 ^{6} - 1}

a^{- x}

a x (x + 1)

(- 5) (- 9)
