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

expand

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

4 x^{2} + 8 x h + 4 h^{2} + 2 x + 2 h - 3

Solution steps

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

Expand

4 (x + h)^{2} : 4 x^{2} + 8 x h + 4 h^{2}

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

Expand

2 (x + h) : 2 x + 2 h

= 4 x^{2} + 8 x h + 4 h^{2} + 2 x + 2 h - 3

(x^{2} y^{3})^{- 2}

18 \cdot (- 2)

(b^{3})^{4} b^{5}

x^{4} + x^{3} + x^{2}

(5^{2})^{6}
