Question

solve for x by factoring.(2x+1)(x+4)=0. show working out im struggling

Answer 1

its 2x-1 my bad

Answer 2

equate the factors to zero so...

2x -1 = 0; x+ 4 = 0

in the first factor... 2x = 1 so x = 1/2
in the second factor x = -4

Answer 3

It is fundamentally the same process as the previous problem
you'd approach each problem in this form the same way.
- factor completely (its already factored completely)
- set each factor = 0
