YOUR QUESTION: f(x)= 2x³ - 14x² + 24x
'Factor each trinomial and find the Zeros.'
(zeros are also known as roots or x-intercepts)
Step one, factor out x. Whenever you can factor out x, one of the roots is 0.
But past that.
I think the problem is with the 2x^2 right?
Whenever the x^2 has a coefficient, use the diamond method!! (:
First of all, look st the trinomial like Ax^2+Bx+C
The capital letters are the coefficients, so in this case A=2, B=-14, and C=24
Now the diamond looks like this (:
AC
factor 1><factor 2
B
The goal is to find two numbers (factors 1 and 2) that add to be B, but multiply to be AC
In this case, you want -6 and -8, because -6 - 8 is -14 and -6(-8) is 48
Now write it out as
2x^2 -6x -8x + 24
Can you see the rest from there? Let me know if you want me to keep going :0
