simplify (4-sqrt(x+5))^2

simplify

(4 - x + 5)^{2}

x - 8 x + 5 + 21

Solution steps

(4 - x + 5)^{2}

Apply Perfect Square Formula:

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

(4 - x + 5)^{2} = 4^{2} - 2 \cdot 4 x + 5 + (x + 5)^{2}

= 4^{2} - 2 \cdot 4 x + 5 + (x + 5)^{2}

Simplify

4^{2} - 2 \cdot 4 x + 5 + (x + 5)^{2} : x - 8 x + 5 + 21

= x - 8 x + 5 + 21

(2 - sin (x))^{2}

2 (csc (x) + sec (x))

A (6, - 5)

2 a^{3} - 8 (b \cdot c) + 6 (d) - 4 (a + e)

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