We assume the two numbers are x and (x+1)
so x^2+(x+1)^2=421
x^2+(x^2+2x+1)=421
2x^2+2x-420=0
According to the formula of quadratic
x=14 or-15
cuz we know the two numbers are integers
so x=14
therefore the other number is 15
To make sure that's correct
14^2+15^2=421
Hope that helps you!!

Answer:
<h2>x = -3</h2>
Step-by-step explanation:
It's a vertical line. Regardless of what point you go to on the line, it always has a value of -3 because it is going vertically (up and down) at -3.
Therefore the equation of a line is x = -3
