Question 729504: I don't understand how to continue this problem. The problem is:
10x^2+10=8-6x
I know that I have to subtract the 8 then the -6x to get 0
I got:
10x^2+6x+2=0
From there, would I have to do the quadratic formula? Because the number you have to square root it by is a negative number and we haven't learned that yet. I tried factoring but I got:
5x^2+3x+1=0
What do I do from here?

you did good job, now just use quadratic formula to solve for
..note that coefficient , and
...plug coefficients in
......you have sqrt of negative number and that means there is no real solutions only imaginary and graph will not intersect with x-axis, and solutions are complex numbers
......write as
...since we have
