P2+5-4(-1)

We add all the numbers together, and all the variables

P^2+9

Back to the equation:

-(P^2+9)


We get rid of parentheses

-P^2+P-9=0

We add all the numbers together, and all the variables

-1P^2+P-9=0

a = -1; b = 1; c = -9;
Δ = b2-4ac
Δ = 12-4·(-1)·(-9)
Δ = -35
Delta is less than zero, so there is no solution for the equation
