factor 8x^2-18x-5

factor

8 x^{2} - 18 x - 5

(4 x + 1) (2 x - 5)

Solution steps

8 x^{2} - 18 x - 5

Break the expression into groups

= (8 x^{2} + 2 x) + (- 20 x - 5)

Factor out

2 x

from

8 x^{2} + 2 x : 2 x (4 x + 1)

Factor out

- 5

from

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

= 2 x (4 x + 1) - 5 (4 x + 1)

Factor out common term

4 x + 1

= (4 x + 1) (2 x - 5)

m (m - 3) = 0

\frac{2 x + 1}{x - 2} \leq 3

∣ 4 x - 5 ∣ = ∣ 2 x + 3 ∣

4 (5 x - 3) < 5 (4 x - 3)

\frac{3 i}{4 - 2 i}
