Using the null factor law solve (2x^2 +3x -2=0).
i know the first step is to take out 2 which makes it (x^2 + 3/2 -1=0) however i don’t know what to do next?

Is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis.
