factor 15x^2-4xy-4y^2

factor

15 x^{2} - 4 x y - 4 y^{2}

(5 x + 2 y) (3 x - 2 y)

Solution steps

15 x^{2} - 4 x y - 4 y^{2}

Break the expression into groups

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

Factor out

3 x

from

15 x^{2} + 6 x y : 3 x (5 x + 2 y)

Factor out

- 2 y

from

- 10 x y - 4 y^{2} : - 2 y (5 x + 2 y)

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

Factor out common term

5 x + 2 y

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

3 x^{2} + x = 2

(\frac{3}{5})^{- 1}

(x - 1)^{\frac{7}{2}} - (x - 1)^{\frac{3}{2}}

∣ x - 9 ∣ = 9

x^{2} + 11 x + 28 \leq 0
