factor 3x^2+21xy-54y^2

factor

3 x^{2} + 21 x y - 54 y^{2}

3 (x - 2 y) (x + 9 y)

Solution steps

3 x^{2} + 21 x y - 54 y^{2}

Factor out common term

3 : 3 (x^{2} + 7 x y - 18 y^{2})

= 3 (x^{2} + 7 x y - 18 y^{2})

Factor

x^{2} + 7 x y - 18 y^{2} : (x - 2 y) (x + 9 y)

= 3 (x - 2 y) (x + 9 y)

2 7^{\frac{- 2}{3}}

100 x^{2} - 81 y^{2}

1 2^{2} + 1 6^{2} = c^{2}

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

x^{2} y - 9 y + 54 - 6 x^{2}
