factor 15x^2-28-x

factor

15 x^{2} - 28 - x

(3 x + 4) (5 x - 7)

Solution steps

15 x^{2} - 28 - x

Write in the standard form

= 15 x^{2} - x - 28

Break the expression into groups

= (15 x^{2} + 20 x) + (- 21 x - 28)

Factor out

5 x

from

15 x^{2} + 20 x : 5 x (3 x + 4)

Factor out

- 7

from

- 21 x - 28 : - 7 (3 x + 4)

= 5 x (3 x + 4) - 7 (3 x + 4)

Factor out common term

3 x + 4

= (3 x + 4) (5 x - 7)

2 p (x) - r (x)

\frac{( f _{4} + f _{2} )}{( x _{1} + x _{4} )}

q^{0.11} (4 sin^{3} (x) - 3 sin (x) + sin^{3} (x))
