Expand and simplify <br> (V5-V2)(V2+V5)

gizmo_the_mogwai [7]

Answer:

Step-by-step explanation:

$(\sqrt{5} - \sqrt{2})(\sqrt{2} + \sqrt{5})\\\sqrt{5} (\sqrt{2} + \sqrt{5}) - \sqrt{2} (\sqrt{2} + \sqrt{5})\\\sqrt{5} * \sqrt{2} + \sqrt{5} * \sqrt{5} - \sqrt{2} * \sqrt{2} +\sqrt{2} * \sqrt{5}\\ \sqrt{5*2} + \sqrt{5*5} - \sqrt{2*2} - \sqrt{2*5}\\\sqrt{10} + \sqrt{25} - \sqrt{4} - \sqrt{10}$

plus root 10 and minus root 10 gets cancel . So,

$\sqrt{25} - \sqrt{4} \\\sqrt{5^{2} } - \sqrt{2^{2} }$

square and root gets cancel

Westkost [7]

Answer:

Step-by-step explanation:

The zeros of the function is the roots and solutions. To find them, factor the equation into two binomials.

$x^2 + x -30\\(x+6)(x-5)$

To solve, set each binomial to 0 and solve for x.

x+6 = 0

x = -6

x-5=0

x=5
