Check whether = (0.91 - sqrt(48.2981))/4.7 and = (0.91 + sqrt(48.2981))/4.7 are solutions to the equation -7.51p^2-7.03p-6.63=-7.94p-5.16p^2-11.68.

Check whether = (0.91 - sqrt(48.2981))/4.7 and = (0.91 + sqrt(48.2981))/4.7 are solutions to the equation -7.51p^2-7.03p-6.63=-7.94p-5.16p^2-11.68.
:
-7.51p^2 - 7.03p - 6.63 = -7.94p - 5.16p^2 - 11.68.
Combine like terms on the right
0 = = -7.94p + 7.03p - 5.16p^2 + 7.51p^2 - 11.68 + 6.63
0 = -.91p + 2.35p^2 - 5.05
Arrange as a quadratic equation
2.35p^2 - .91p - 5.05 = 0
Find the solutions using the quadratic formula

where x=p; a=2.35; b=-.91; c=-5.05

Minus a minus is a plus

and

:
We proved that, indeed, these are the solutions to the given equation
