Question

Factor the following trinomial:

3x^2 − xy − 52y^2

Answer 1

same as before

3 x -52 = -156

find the factors of -156 that add to -1

so -13 and 12

so its

(3x +12y)(3x - 13)
----------------
3

you can finish from here

Answer 2

oops should be -13y

Answer 3

uhh, not sure if I did it correctly, but I got:
\[\frac{ 3(x+4y)x(3-13y) }{ 3 }\]

Answer 4

almost, 3 from the 1st binomial is correct... byt x isn't a common factor in the 2nd binomial

the solution is

(x + 4y)(3x - 13y)

Answer 5

Thank you so much ! :)
