expand (x-3)(2x^z-x+5)

expand

(x - 3) (2 x^{z} - x + 5)

- x^{2} - 6 x^{z} + 2 x^{1 + z} + 8 x - 15

Solution steps

(x - 3) (2 x^{z} - x + 5)

Distribute parentheses

= x \cdot 2 x^{z} + x (- x) + x \cdot 5 - 3 \cdot 2 x^{z} - 3 (- x) - 3 \cdot 5

Simplify

x \cdot 2 x^{z} + x (- x) + x \cdot 5 - 3 \cdot 2 x^{z} - 3 (- x) - 3 \cdot 5 : - x^{2} - 6 x^{z} + 2 x^{1 + z} + 8 x - 15

= - x^{2} - 6 x^{z} + 2 x^{1 + z} + 8 x - 15

\frac{( 3 x y )}{( x \cdot y ^{2} )}

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

16 x y^{3} - 64 x y

\frac{( 3 - x )}{( 4 x - 12 )}

(\frac{3 x + 1}{3 x})^{3}
