expand (7a^6+12a)^2

expand

(7 a^{6} + 12 a)^{2}

49 a^{12} + 168 a^{7} + 144 a^{2}

Solution steps

(7 a^{6} + 12 a)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(7 a^{6} + 12 a)^{2} = (7 a^{6})^{2} + 2 \cdot 7 a^{6} \cdot 12 a + (12 a)^{2}

= (7 a^{6})^{2} + 2 \cdot 7 a^{6} \cdot 12 a + (12 a)^{2}

Simplify

(7 a^{6})^{2} + 2 \cdot 7 a^{6} \cdot 12 a + (12 a)^{2} : 49 a^{12} + 168 a^{7} + 144 a^{2}

= 49 a^{12} + 168 a^{7} + 144 a^{2}

3 (x + 4) - (2 x + 7)

1 \frac{2}{3} \cdot 1 \frac{2}{3}

\frac{a ^{2} - 1}{a + 1}

\frac{6}{4 x} + \frac{3}{2 x}
