Question 750021: x intercept of a quadratic function are -3 and 5 what is the equation of its axis of symmetric.
2.x^2-7x+12=0 how many real solution are there.
3.x=2 x=-3 what r the x intercept of the related quadratic equation.
4.(x-12) (x+17)=0

You can put this solution on YOUR website!
#3, that is not clear.

#2, use the discriminant. ax%5E2%2Bbx%2Bc=0, the discriminant is b%5E2-4ac.. This will either be positive, zero, or negative.
%28-7%29%5E2-4%2A1%2A12------------------How is it by order to zero? .... and this means???



I'm letting you find the related information about this in your book and hoping you are not bothered that I do not finish this for you.
