factor 3x^2+2xy-y^2

factor

3 x^{2} + 2 x y - y^{2}

(3 x - y) (x + y)

Solution steps

3 x^{2} + 2 x y - y^{2}

Break the expression into groups

= (3 x^{2} - x y) + (3 x y - y^{2})

Factor out

x

from

3 x^{2} - x y : x (3 x - y)

Factor out

y

from

3 x y - y^{2} : y (3 x - y)

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

Factor out common term

3 x - y

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

1 - y = \frac{( 0.75 - 0.5 y )}{0.9}

10 a^{2} + 10 a - 20

7^{2} + x^{2} = 2 5^{2}

x^{2} + \frac{14}{3} x + \frac{49}{9}

\frac{1}{3 ^{- 2}}
