expand 3(x+h)^2+4(x+h)-3

expand

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

3 x^{2} + 6 x h + 3 h^{2} + 4 x + 4 h - 3

Solution steps

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

Expand

3 (x + h)^{2} : 3 x^{2} + 6 x h + 3 h^{2}

= 3 x^{2} + 6 x h + 3 h^{2} + 4 (x + h) - 3

Expand

4 (x + h) : 4 x + 4 h

= 3 x^{2} + 6 x h + 3 h^{2} + 4 x + 4 h - 3

\frac{( 9 - x ^{- 2} )}{( 3 + x ^{- 1} )}

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

- \frac{1}{10} + \frac{7}{8}

- \frac{1}{- 5}

\frac{- 45}{5}
