expand-3(x+h)^2

expand

- 3 (x + h)^{2}

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

Solution steps

- 3 (x + h)^{2}

Expand

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

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

Apply the distributive law:

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

- 3 (x^{2} + 2 x h + h^{2}) = - 3 x^{2} - 3 \cdot 2 x h - 3 h^{2}

= - 3 x^{2} - 3 \cdot 2 x h - 3 h^{2}

Multiply the numbers:

3 \cdot 2 = 6

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

\frac{x + 2}{2 x ^{2} + 13 x + 20} - \frac{x + 3}{2 x ^{2} + 13 x + 20}

\frac{2 x ^{2} - 3 x + 1}{2 x ^{2} + x - 1}

\frac{x ^{2} + 17 x + 70}{x ^{2} + 6 x - 40}
