True or false:
The solutions, roots, x-intercepts, and zeros of a quadratic equation are all the same thing.
The solutions, roots, x-intercepts, and zeros of a quadratic equation are all the same thing.
a)
True
b)
False, because the solution and root are the same but the x-intercept and zero are different
c)
False, because the x-intercept and root are the same but the zero and solution are different
d)
False, they are all different

6.
What should you do first if you wanted to solve this equation using the quadratic formula?
2x2 + 6x - 14 = 8
a)
Divide everything by 2
b)
Write down: a=2, b=6, c=-14
c)
Subtract 8 from both sides
