Answer:
The factors are 3 and -9
Step-by-step explanation:
The given trinomial is
.
We need to find two factors. We know that,
3(9) = 27
So,
can be written as :
as two factors add up to get -6 and multiply to get -27.
Hence, the factors are 3 and -9.
To prove that x = 2 in the equation given, first, we write the given.
(4) Given: (A) 12 - x = 20 - 5x
Then, add 5x to both sides of the equation,
(3) Addition property of equality: (B) 12 + 4x = 20
Then, subtract 12 from both sides of the equation
(2) Subtraction property of equality: (C) 4x = 8
Lastly, divide both sides by 4
(1) Division property of equality : (D) x = 2
