factor 5x^2-x-4

factor

5 x^{2} - x - 4

(5 x + 4) (x - 1)

Solution steps

5 x^{2} - x - 4

Break the expression into groups

= (5 x^{2} + 4 x) + (- 5 x - 4)

Factor out

x

from

5 x^{2} + 4 x : x (5 x + 4)

Factor out

- 1

from

- 5 x - 4 : - (5 x + 4)

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

Factor out common term

(5 x + 4) : (5 x + 4) (x - 1)

= (5 x + 4) (x - 1)

2 x + 15 = x + 15

\frac{e ^{a}}{e ^{b}}

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

1 - w \geq - 1

4 - 3 x - x^{2} = 2 x + 8
