simplify (x+2sqrt(5))(x-2sqrt(5))(x+sqrt(3))

simplify

(x + 25) (x - 25) (x + 3)

(x^{2} - 20) (x + 3)

Solution steps

(x + 25) (x - 25) (x + 3)

Apply Difference of Two Squares Formula:

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

(x + 25) (x - 25) = x^{2} - (25)^{2}

= (x^{2} - (25)^{2}) (x + 3)

Simplify

x^{2} - (25)^{2} : x^{2} - 20

= (x^{2} - 20) (x + 3)

(1 + \frac{1}{4} y)^{6}

(x^{2} - 1) y^{3} d x + x^{2} d y

(s + 4 - 7 i)^{2}

\frac{1}{( 7 - 5 \cdot i \cdot x ) ^{7}}

(x + Δ x)^{2} - 2 (x + Δ x) + 2
