1. campbell_st

there are no real solutions to this quadratic...

2. campbell_st

the quadratic is positive definite... to check the nature of the solutions use the discriminant $\Delta = b^2 - 4ac$

3. Eda2012

use this formula.... $ax ^{2}-bx+c=0$ $x = \frac{ -b \pm \sqrt{b ^{2}-4ac} }{ 2a }$

4. campbell_st

you may use the formula but you won't get real solutions, you will get complex solutions.

5. Eda2012

why dont use completing square...and then plot the graph...then find the intersection of the graph...

how do i get a real solution
