example click on the question mark
(6x³ -9x²) +(4x – 6)
3x²(2x-3) + 2(2x-3)
in your parenthesis.
write what you have left
3x² + 12 x + 9
Hint: (All the terms have a common factor of 3)
3 (x² +4x +3)
A² +2AB+B² = (A+B)²
x²+ 6x +9 = (x+3)²
Mult. First and last terms
North and South
North and add to the South and
write those two numbers in the East
Write the middle term
(the number in front of x²)
number if you can and if it is still a fraction bring the bottom number up in front of the x
(a²-b²) = (a+b) (a-b)
(x² -4) = (x +2) (x-2)
You have completely factored your polynomial! Good Job!
