Use the Quadratic Formula to find the x-intercepts of the equation \mathbf{$\mathbf{ax^2 + bx + c = 0}$} \text{ where } \mathbf{$\mathbf{a=1, b=-7, c=12}$}.
Solve two linear equations and determine how to get one from the other.
A. 2x−1+3x=0
B. 5x−1=0
1) How can we get Equation B from Equation A?
(A) Add/subtract the same quantity to/from both sides
(C) Rewrite one side (or both) by combining like terms
