What are the roots of the polynomial equation?
x2−14x−32=0
3 answers:
We are given the quadratic equation :
Now let us use AC method to factorise it.
Step 1:
Find product of A and C
A=1 and C =-32
A*C =-32
Step 2:
Find factors of -32 such that they add up to give -14.
Factors of -32 that add up to give -14 are -16 and 2.
Step 3:
Rewrite the equation using factors found in step 2.
Step 4:
Factoring by grouping.
Step 5:
Find roots.
x-16=0 gives x=16
x+2=0 gives x=-2
Answer : Roots of the given Polynomial equation are 16 and -2.

We can easily factor that into:
(x +2) * (x -16) = 0
x1 = -2
x2 = 16
