If you are looking at a graph of a quadratic equation, how do you determine where the solutions are?
Do you mean the zeroes?
i am just starting on quadratic equations i think its asking me what i would look for to determine a solution
The solutions are synonymous with the zeros or the roots. The x-intercepts are the points where the graph crosses the x axis. The x coordinates of these points will represent the solutions or zeros of the quadratic equation.
this stuff is enough to melt the brain
Ok, so this is referring to finding the zeroes. To do this, you simply split the quadratic equation into two separate equations and and solve for x
Ex: if the equation was: x^2-6x+9, you would split it into: (x-3)(x-3). This means the zero is at 3. It also means that at 3, there is a multiplicity since x=3 happens twice
oh boy cant wait to do this more
ty for your help i think im gonna need to post some problems and see how to work them
did you see the other post i had i can post it here if you know it
