expand (x^2-2x+1)(1+0.1x)

expand

(x^{2} - 2 x + 1) (1 + 0.1 x)

0.1 x^{3} + 0.8 x^{2} - 1.9 x + 1

Solution steps

(x^{2} - 2 x + 1) (1 + 0.1 x)

Distribute parentheses

= x^{2} \cdot 1 + x^{2} \cdot 0.1 x - 2 x \cdot 1 - 2 x \cdot 0.1 x + 1 \cdot 1 + 1 \cdot 0.1 x

Simplify

x^{2} \cdot 1 + x^{2} \cdot 0.1 x - 2 x \cdot 1 - 2 x \cdot 0.1 x + 1 \cdot 1 + 1 \cdot 0.1 x : 0.1 x^{3} + 0.8 x^{2} - 1.9 x + 1

= 0.1 x^{3} + 0.8 x^{2} - 1.9 x + 1

\frac{50 s ^{3} + s ^{2} + s + 100}{s ^{2} ( s ^{2} + s + 100 )}

\frac{( 3 + 2 x ) ^{2}}{2}

\frac{( x + 4 )}{( x + 2 ) ^{2}}

\frac{( s + 5 ) ( s + 8 ) ( s + 10 ) ( s + 15 )}{( s + 20 )}

(y^{2} + 2 x^{2}) d x
