simplify (5-sqrt(15-x))^2

simplify

(5 - 15 - x)^{2}

- x - 10 15 - x + 40

Solution steps

(5 - 15 - x)^{2}

Apply Perfect Square Formula:

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

(5 - 15 - x)^{2} = 5^{2} - 2 \cdot 5 15 - x + (15 - x)^{2}

= 5^{2} - 2 \cdot 5 15 - x + (15 - x)^{2}

Simplify

5^{2} - 2 \cdot 5 15 - x + (15 - x)^{2} : - x - 10 15 - x + 40

= - x - 10 15 - x + 40

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

(f (x) = 3 x^{2} + x - 4) (5.76)

\frac{2 x ^{2} + 4 x - 8}{x ( x - 2 ) ^{2}}

(x + \frac{3}{10}) (x - \frac{3}{10})

\frac{4 ( - 2 + 3 x )}{3 x}
