Juan began solving the proportion
=
by using cross products.
He continued correctly solving the proportion until he got stuck. Analyze Juan's work shown below.
-4(1) = (-3) ( +6)
-4 = 22 + 3.0 - 18
0= x2 + 3x - 14
What step should juan take next and why?
Juan should use the quadratic formula to find the solutions since the expression is not factorable
over the integers.
Juan should isolate the constant because he can then factor the remaining terms and use the
Zero Product Property to solve for 2.
Juan should factor the expression to find the roots because the coefficient of the x term is 1 so
it is easily factored.
term because he can then simplify the remaining expression to solve
Juan should isolate the
for a
term because he can then take the square root of both sides of the
Juan should isolate the
equation to solve for 2.
