replace f(x) with y

.

y=x2+x−30

To find the roots of the equation, replace y

with 0

and solve.

0=x2+x−30

Rewrite the equation as x2+x−30=0

x2+x−30=0

Factor x2+x−30

using the AC method.

(x−5)(x+6)=0

Set x−5

equal to 0 and solve for x

x=5

Set x+6

equal to 0 and solve for x

x=−6

The solution is the result of x−5=0

and x+6=0

x=5,−6

Hope this helps!
