I need help. Medal given.
How do I factor
2x/\2-13x+20
I need explanations and /\ means to the power of... So its 2x squared

Answer 1

well your question is 2x^2 -13x + 20
split -13 into -5 -8

that gives us

2x^2 -5x -8x +20 group the first two and last two *take - sign out in the second this reverses the sign inside the brackets!!

(2x^2 - 5x) -(8x -20) take x common from first set and 4 from the second!
x(2x-5) -4(2x -5)

now take 2x-2 common which gives

(2x-5)(x-4) this is your answer!!

get whats goin on here? =D
