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

expand

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

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

Solution steps

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

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) - 2

Expand

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

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

- \frac{1}{2 i}

5 x^{2} - 10 x^{2}

- 9 \cdot 5

y^{5} - 81 y

(- 12) + 7
