factor 27ab-9b^2-20a^2

factor

27 ab - 9 b^{2} - 20 a^{2}

(5 a - 3 b) (- 4 a + 3 b)

Solution steps

27 ab - 9 b^{2} - 20 a^{2}

Group by common factors

= - 20 a^{2} + 27 ab - 9 b^{2}

Break the expression into groups

= (- 20 a^{2} + 12 ab) + (15 ab - 9 b^{2})

Factor out

- 4 a

from

- 20 a^{2} + 12 ab : - 4 a (5 a - 3 b)

Factor out

3 b

from

15 ab - 9 b^{2} : 3 b (5 a - 3 b)

= - 4 a (5 a - 3 b) + 3 b (5 a - 3 b)

Factor out common term

5 a - 3 b

= (5 a - 3 b) (- 4 a + 3 b)

∣ p + 4 ∣ \leq 8

\frac{\frac{1}{2}}{4}

y, 2 x^{2} + 2 y^{2} - 2 x + 6 y + 5 = 0

5 p - 14 = 8 p + 4

(- 36)^{\frac{3}{2}}
