Are these equations equal to zero?
If so, then I noticed that each one factors quite easily.
I will do the last one
3m^2 + 5m - 2 =0
(3m - 1)(m + 2) = 0
3m-1 = 0 or m+2 = 0
m = 1/3 or m = -2
do the others the same way.
You can check your answers by subbing them back in.
e.g. if m = -2
LS = 3(4) + 5(-2) - 2
= 12 - 10 - 2
so my answer of m=-2 is correct
you are missing the exponents
if (a) should be 2x^2 - 7x - 5
a) 2x^2 - 7x - 5
does not factor, solve by using the quadratic formula or completing the square
if you are stuck, post your work and someone will help
tutors do not do your homework
