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

simplify

(x + 25)^{2}

x + 45 x + 20

Solution steps

(x + 25)^{2}

Apply Perfect Square Formula:

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

(x + 25)^{2} = (x)^{2} + 2 x \cdot 25 + (25)^{2}

= (x)^{2} + 2 x \cdot 25 + (25)^{2}

(x)^{2} = x

2 x \cdot 25 = 45 x

(25)^{2} = 20

= x + 45 x + 20

(cos (x) + i sin (x))^{3}

(- 5, 8) y (- 5, - 6)

(csc (x) + 1) tan (x) - sec (x)

(1 + i)^{9}

(x - 2) (x + 2)
