Find the factors of 3x2 − 33x + 84
4 months ago
Q:
Find the factors of 3x2 − 33x + 84
Accepted Solution
A:
For these ones I just play around with what I can divide 84 by to equal -33 in the middle. I decided to divide 84 by 4 because it was an even number.
84/4=21
21+ (3*4)= 33
Answer: (x-4)(3x-21)
