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

expand

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

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

Solution steps

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

Expand

3 (x + h) : 3 x + 3 h

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

\frac{- 10}{2 + 14}

e^{- l n (x) - x}

(4 x^{2} + 2 x + 1) - (- 5 x^{2} + 8 x - 8)

\frac{7 ^{12}}{7 ^{2}}
