simplify (x^2-9y^2)-(3x-9y)

simplify

(x^{2} - 9 y^{2}) - (3 x - 9 y)

x^{2} - 9 y^{2} - 3 x + 9 y

Solution steps

(x^{2} - 9 y^{2}) - (3 x - 9 y)

Apply rule:

(a) = a

(x^{2} - 9 y^{2}) = x^{2} - 9 y^{2}

= x^{2} - 9 y^{2} - (3 x - 9 y)

Apply the distributive law:

- (a - b) = - a + b

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

= x^{2} - 9 y^{2} - 3 x + 9 y

\frac{( 2 u ^{2} ) ^{3}}{3 u ^{5}}

4 + 2

(2 q - 4)^{2}

2 x z + 6 y + 2 x y + 6 z
