x2+6-27=0

Answer 1

Explanation:

`x^(2) +6x-27=0`

We must find two number that multiply to -27 and add to positive 6.

Since the middle term is positive, the bigger term should be positive and the smaller term should be negative.

The factors of 27 are:

±1,27

±3,9

Applying the second sentence, the numbers that add to positive 6 are 9 and -3.

So, our factors are

(x+9) (x-3)=0

You are done!!!!

If you want to solve for x,

Set each expression equal to zero

x+9=0

x=-9

x-3=0

x=3
