Basically, what i had to do in this section was to solve for x. After a couple pages, i ran into some problems. My first difficulty was:
1/2(x+7)^2=8
Steps:
1. 1/2(x^2+49)=8
2. (x^2+49)=16
3. x^2=-33
4. x=(square root of)-33
5. x=(sq. rt of)-11 * (sq. rt of)3
I cant figure this one out! Please tell me what went wrong in my steps. Or if i can simplify any further.
There was one other:
3/5(x-1/2)^2=4
I pretty much simplified it the same was as before and got to x=(sq. rt of) 924/12 which i further simplified to 2(sq rt)3*(sq rt)11*(sq rt)7. Im having the same trouble here! Thanks in advance!!!
