Are these equations equal to zero?
If so, then I noticed that each one factors quite easily.
I will do the last one
g)
3m^2 + 5m  2 =0
(3m  1)(m + 2) = 0
3m1 = 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
= 0
= RS
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
