Answer: 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!

Answer:
See below.
Step-by-step explanation:
2x^2 - 2x - 12 = 0
2 is a factor so we write:
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0
The solutions are  x = -2 and x = 3 which means that the graph of the equation passes through the x-axis at (-2, 0) and (3, 0). The graph is a parabola  opening upwards.  Also the multiplier of 2 produces a vertical transformation (stretching) of the graph of x^2 - x - 6.
