simplify (2+sqrt(-y^2+y-4))^2

simplify

(2 + - y^{2} + y - 4)^{2}

- y^{2} + y + 4 - y^{2} + y - 4

Solution steps

(2 + - y^{2} + y - 4)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

2^{2} + 2 \cdot 2 - y^{2} + y - 4 + (- y^{2} + y - 4)^{2} : - y^{2} + y + 4 - y^{2} + y - 4

= - y^{2} + y + 4 - y^{2} + y - 4

16 (x - 1)^{2} + 16 (- \frac{1}{4} x + \frac{1}{4})^{2}

(2 x^{4} - 1)^{'} \cdot (5 x^{3} - 6) + (5 x^{3} - 6)^{'} \cdot (2 x^{4} - 1)

- K L + (U (t - \frac{e ^{x t} - 1}{x}))

(2 - 3) (2 + 46)

(\frac{n}{2} - \frac{2}{n})^{2}
