on a math test, jun was asked to find the point(s) where the equations y = x2 + 10x – 6 & y = 7x – 2 intersect.
jun’s solution is shown below.
jun’s solution:
y = x2 + 10x – 6
y = 7x – 2
x2 + 10x – 6 = 7x – 2
x2 + 3x – 4 = 0
(x – 1) (x + 4) = 0
x = 1 or x = -4
the graphs intersect at (-4, 0) and (1, 0)
a) is jun’s solution correct? explain why or why not.
b) if jun’s solution is incorrect, show the correct work for this problem.
