simplify (3x+sqrt(7))^2

simplify

(3 x + 7)^{2}

9 x^{2} + 67 x + 7

Solution steps

(3 x + 7)^{2}

Apply Perfect Square Formula:

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

(3 x + 7)^{2} = (3 x)^{2} + 2 \cdot 3 x 7 + (7)^{2}

= (3 x)^{2} + 2 \cdot 3 x 7 + (7)^{2}

(3 x)^{2} = 9 x^{2}

2 \cdot 3 x 7 = 67 x

(7)^{2} = 7

= 9 x^{2} + 67 x + 7

(2 + x - 2)^{2}

(\frac{x}{3} - \frac{y}{2})^{5}

(2 (y - x) - 1 - 1 - (y - x)) l e f t (x, 1, - y)

\frac{2 ( π + 180 )}{180}

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