expand (6a-7b^2)(-3a+9b^2)

expand

(6 a - 7 b^{2}) (- 3 a + 9 b^{2})

- 18 a^{2} + 75 a b^{2} - 63 b^{4}

Solution steps

(6 a - 7 b^{2}) (- 3 a + 9 b^{2})

Apply FOIL method

(6 a - 7 b^{2}) (- 3 a + 9 b^{2}) : - 18 a^{2} + 75 a b^{2} - 63 b^{4}

= - 18 a^{2} + 75 a b^{2} - 63 b^{4}

[(x^{2} y^{- 2})^{- 1}]^{- 1}

(1 - 7 a) - (7 a - 16)

lo g_{0.2} (125)

\frac{1 - cos ( 2 x )}{1 + cos ( 2 x )}

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