i know it will be w+ ? and w-?

What do you think you should do first? I literally helped you step-by-step in two prior answers so you should have some sort of understanding.

i dont understand how to take the square root of -9/4

5. anonymous

i know it will be 3/2

Use the following rule: $$x^2-b^2=(x+\sqrt b)(x-\sqrt b)$$

7. anonymous

so will the answer be (w-3/2)(w+3/2)
