Answer: ![\bold{x = \dfrac{5}{7},\quad x=2}](https://tex.z-dn.net/?f=%5Cbold%7Bx%20%3D%20%5Cdfrac%7B5%7D%7B7%7D%2C%5Cquad%20x%3D2%7D)
<u>Step-by-step explanation:</u>
y = 28x² - 76x + 40
0 = 28x² - 76x + 40 <em>finding the x-intercepts, so replaced y with 0</em>
0 = 4(7x² - 19x + 10) <em>factored out the common term (4)</em>
0 = 7x² - 19x + 10 <em>divided both sides by 4</em>
0 = 7x² -14x -5x + 10 <em>replaced -19x with -14x and -5x</em>
0 = 7x(x - 2) -5(x - 2) <em>factored out common terms from each side</em>
0 = (7x - 5) (x - 2) <em> "undistributed" factors</em>
0 = 7x - 5 and 0 = x - 2 <em>applied zero product property</em>
x =
and x = 2 <em>solved for x</em>
