Mathieu is finding the x-intercepts of the function f(x)=x^2+4x+3. his world is shown below.
(in the photo)
the answer is:
(he set the factored expressions equal to each other)
i learned that the hard way trial and error > ~<
which error did mathieu make?
he factored incorrectly.
he did not use the constant as the x-intercept.
(he set the factored expressions equal to each other.)
he incorrectly solved the equation x + 3 = x + 1.
