What is the solution to this Equation? x^2 +x-20=0

x = -5, and x=4

Step-by-step explanation:

You can factor the quadratic out by factoring to get

(x+5)(x-4) = 0

then solve for x

x = -5, 4

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
