factor 15x^2+13x-20

factor

15 x^{2} + 13 x - 20

(5 x - 4) (3 x + 5)

Solution steps

15 x^{2} + 13 x - 20

Break the expression into groups

= (15 x^{2} - 12 x) + (25 x - 20)

Factor out

3 x

from

15 x^{2} - 12 x : 3 x (5 x - 4)

Factor out

5

from

25 x - 20 : 5 (5 x - 4)

= 3 x (5 x - 4) + 5 (5 x - 4)

Factor out common term

5 x - 4

= (5 x - 4) (3 x + 5)

\frac{1}{19} = \frac{x + 1}{5}

\frac{2}{3} + \frac{5}{6} \cdot \frac{1}{2}

x^{2} = 360

3 x + 1 - 2 x - 1 = 1

(1 + x^{2})^{- \frac{1}{2}}
