The values of x for which the denominator is equal to zero is +2 or -2-2
<h3 /><h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given function is: y=
As, for the denominator is equal to zero. We have
x²-4=0
x²=4
x=√4
x= ± 2
Thus, by putting either x= +2 or x= -2 in denominator which will gives the denominator equals to zero.

Hello,
x²-13x-30=x²+2x-15x-30=x(x+2)-15(x+2)=(x+2)(x-15)
Roots are -2 and 15
