factor 4x^2+16x+15

factor

4 x^{2} + 16 x + 15

(2 x + 3) (2 x + 5)

Solution steps

4 x^{2} + 16 x + 15

Break the expression into groups

= (4 x^{2} + 6 x) + (10 x + 15)

Factor out

2 x

from

4 x^{2} + 6 x : 2 x (2 x + 3)

Factor out

5

from

10 x + 15 : 5 (2 x + 3)

= 2 x (2 x + 3) + 5 (2 x + 3)

Factor out common term

2 x + 3

= (2 x + 3) (2 x + 5)

x^{4} + 2 x^{2} - 24

9 x^{2} - 6 x - 4 = - 5

\frac{- 5 x ^{3} y}{15 x y ^{3}}

- 11 < 5 + 4 x

- (x + 3) + \frac{3}{4} x + 5 = 0
