expand (5x^2-3x)(8x^2+4x)

expand

(5 x^{2} - 3 x) (8 x^{2} + 4 x)

40 x^{4} - 4 x^{3} - 12 x^{2}

Solution steps

(5 x^{2} - 3 x) (8 x^{2} + 4 x)

Apply FOIL method

(5 x^{2} - 3 x) (8 x^{2} + 4 x) : 40 x^{4} - 4 x^{3} - 12 x^{2}

= 40 x^{4} - 4 x^{3} - 12 x^{2}

\frac{5 80}{32}

(4 q^{4} + 3 q^{2} + 8 q) + (5 q^{3} - 2 q^{2} - q)

\frac{7}{x}

\frac{3 !}{0 ! ( 3 - 0 ) !}
