factor 6a^2-ab-15b^2

factor

6 a^{2} - ab - 15 b^{2}

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

Solution steps

6 a^{2} - ab - 15 b^{2}

Break the expression into groups

= (6 a^{2} + 9 ab) + (- 10 ab - 15 b^{2})

Factor out

3 a

from

6 a^{2} + 9 ab : 3 a (2 a + 3 b)

Factor out

- 5 b

from

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

= 3 a (2 a + 3 b) - 5 b (2 a + 3 b)

Factor out common term

2 a + 3 b

= (2 a + 3 b) (3 a - 5 b)

b^{3} - \frac{1}{64}

3.2 x^{2} + 7 x - 21 = 0

\frac{5 a ^{2} - 46 a + 9}{a - 9}

x^{2} - 0.3 x - 0.04 = 0

- 0.2 x^{2} - 1 0^{- 4.7} x + 1 0^{- 4.7} = 0
