Given the quadratic equation:
[tex]\text{ x}^2\text{ - 8x + 15 = 0}[/tex]Recall that the standard form of a quadratic equation is:
[tex]\text{ ax}^2\text{ + bx + c = 0}[/tex]The given equation is already in standard form, therefore, we can now proceed identifying what is a, b and c.
We get,
[tex]\text{ ax}^2\text{ + bx + c = 0}[/tex][tex]\text{ (1)x}^2\text{ + (-8)x + (15) = 0}[/tex]Therefore,
a = 1
b = -8
c = 15
