expand 7(x+h)^2

expand

7 (x + h)^{2}

7 x^{2} + 14 x h + 7 h^{2}

Solution steps

7 (x + h)^{2}

Expand

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

= 7 (x^{2} + 2 x h + h^{2})

Apply the distributive law:

m (a + b + c) = ma + mb + m c

7 (x^{2} + 2 x h + h^{2}) = 7 x^{2} + 7 \cdot 2 x h + 7 h^{2}

= 7 x^{2} + 7 \cdot 2 x h + 7 h^{2}

Multiply the numbers:

7 \cdot 2 = 14

= 7 x^{2} + 14 x h + 7 h^{2}

x^{2} (x^{\frac{1}{2}})

2 - 14

\frac{3 ( 11 )}{2}

24 + 6

\frac{108 a ^{8}}{b ^{2}}
