How do you find the solution to the quadratic equation #x^2+8x+7=0#?
from the equation
a=1 b=8 c=7
put your numbers in the formula
This give you two real solutions.
If inside the square root there was something negative, like
if inside the square root there was a 0 you would have only one solution right?
so your equation has the answers x=-1 and x=-7 , you can see if it is right by putting the x inside your equation.
Never forget the signe of the constants a b and c and ALWAYS before start solving equale to 0, i mean, all the ehing different to zero have to be at the right or left of the equal signe, you can't start solving from
