Answer:
<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>
