Question

how you can use the graph of the quadratic function f(x) to solve the equation f(x) = 0

Answer 1

Do you have a specific graph? What is x when f(x) = 0?

Answer 2

i think the parabola that has the vertex of (0,0)

Answer 3

the solutions will be the intersections of the graph with the x axis
for example if the graph intersects at -3 and 2 the equation will be (x+3)(x-2)=x^2+x-6

Answer 4

the solutions will be the x values at the intersections

Answer 5

so basically you just need to apply the equal real roots?

Answer 6

thank you very much for your help
