expand q(x)(x^2-9=0)

expand

q (x) (x^{2} - 9 = 0)

x^{2} q (x) - 9 q (x) = 0

Solution steps

q (x) (x^{2} - 9 = 0)

= q (x) (x^{2} - 9 \cdot 0 =)

Apply the distributive law:

a (b - c) = ab - a c

a = q (x), b = x^{2}, c = 9 = 0

q (x) x^{2} - q (x) \cdot 9 = 0

x^{2} q (x) - 9 q (x) = 0

e^{2 x^{2} - 3 x + 2} (4 x - 3)

\frac{3 ( 99 + 2 165 )}{277}

(a x^{2} + b x) (d cos (x) + e sin (x))

\frac{x ^{2} + 20 x + 1}{( x + 1 ) ^{2}}

4 e^{x} (e^{2 x} - e^{x})
