# Quadratic formula: Solving equations without a ‘b’?

Directions: Use the quadratic formula to solve each equation. There arose two problems in this section that I found did not have a ‘b’ value, and I’m not sure how to solve them with the quadratic formula. The equations are as follows: 3x^2-8=0 x^2-5=0 You don’t necessarily have to solve them for me, but at [...]

# Does the quadratic formula find the POIS or the x intercepts when given two equations?

say you have y=x^2+9x+20 and y=6 so you do 6=x^2+9x+20 -6 -6 ————- 0=x^2+9x+14 then do the quadratic formula and get x=-7 x=-2 so, is this the x’s for poi’s or x int’s
