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

simplify

(x + 2 - 7)^{2}

x - 14 x + 2 + 51

Solution steps

(x + 2 - 7)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(x + 2)^{2} - 2 x + 2 \cdot 7 + 7^{2} : x - 14 x + 2 + 51

= x - 14 x + 2 + 51

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

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

a (e^{b x^{2}} + 2 b e^{b x^{2}} x^{2})

2 (3 s + 1) (s + \frac{1}{14})
