I need help!! Given a quadratic function, which choice explains the meaning of the zeros graphically?

a) f(x)= (x+p) (x+q) where p and a correspond to the x-intercepts

b) f(x)= (x-p) (x-q) where p and a correspond to the x-intercepts

c) f(x)= (x-p) (x-q) where p and a correspond to the vertex

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
