expand (3d^4-7e^3)^2

expand

(3 d^{4} - 7 e^{3})^{2}

9 d^{8} - 42 e^{3} d^{4} + 49 e^{6}

Solution steps

(3 d^{4} - 7 e^{3})^{2}

Apply Perfect Square Formula:

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

a = 3 d^{4}, b = 7 e^{3}

= (3 d^{4})^{2} - 2 \cdot 3 d^{4} \cdot 7 e^{3} + (7 e^{3})^{2}

Simplify

(3 d^{4})^{2} - 2 \cdot 3 d^{4} \cdot 7 e^{3} + (7 e^{3})^{2} : 9 d^{8} - 42 e^{3} d^{4} + 49 e^{6}

= 9 d^{8} - 42 e^{3} d^{4} + 49 e^{6}

\frac{cos ( x )}{( tan ( x ) ) ( 1 - sin ( x ) )}

(x - 25)^{2}

\frac{( x + 3 ) ( x - 2 )}{( x + 2 ) ( x - 1 )}

(e^{i x} - e^{- i x})^{2}

(x + 2) (2 - \frac{3}{x})^{6}
