jim_thompson5910 · Answer

2u^2-5u+2=0


2u^2 - 4u - u+2=0

Note: -4 and -1 multiply to 2*2 = 4 and add to -5


(2u^2-4u) + (-u + 2) = 0


2u(u-2) -1(u - 2) = 0


(2u-1)(u-2) = 0


I'll let you take over from here.

how do i know to change the -5u into -4u-1u

jim_thompson5910 · Answer

You multiply the first coefficient by the last term to get: 2*2 = 4

Then you look for two numbers that multiply to that last result AND add to the middle coefficient of -5

These two numbers are -4 and -1


So this means that you break up -5u into -4u - 1u or just -4u - u
