factor 15+a^2b+5b+3a^2

factor

15 + a^{2} b + 5 b + 3 a^{2}

(b + 3) (a^{2} + 5)

Solution steps

15 + a^{2} b + 5 b + 3 a^{2}

Group by common factors

= a^{2} b + 3 a^{2} + 5 b + 15

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

Factor out

a^{2}

from

a^{2} b + 3 a^{2} : a^{2} (b + 3)

Factor out

5

from

5 b + 15 : 5 (b + 3)

= a^{2} (b + 3) + 5 (b + 3)

Factor out common term

b + 3

= (b + 3) (a^{2} + 5)

\frac{1}{( \frac{1}{a} + \frac{1}{b} )}

(a - b)^{7} + 2 a^{3} b^{3}

\frac{( x ^{2} \cdot x ^{- 3} \cdot x ^{7} )}{( x ^{6} \cdot x ^{- 5} \cdot x ^{4} )}

\frac{f ( x ) 1}{3 x - 5}

12 x^{6} - 7 x^{3} \cdot y - 10 y^{2}
