Preview: ... ues go where. For the first two problems, try and figure out values for the variables in an expression like (a x + b) (c x + d)<br><br>If you expand that out to a quadratic you get<br><br>a c x^2 + (a d + b c) x + b d<br><br>a. 16x^2 + 40x + 25 = (4x + 5)^2<br><br>How did we get this? Well, from our pattern above b d = 25, but ...

Preview: ... + 80<br><br>Subtracting x^2 from each side,<br>8x + 16 = 4x + 80<br><br>subtracting 4x from each side,<br>4x + 16 = 80<br><br>Subtracting 16 from each side<br>4x = 64<br><br>Dividing by 4,<br>x = 16<br><br>So the three integers are 16, 18 , and 20. Check that the sequare of 20 is 76 more than the square of 18:<br><br>18^2 = 324 <br>20^2 = 400 = 324 + 76<br><br>Check.<br><br>b. Let the width in feet be denoted as x. Then the length is x +50. If we know that the length of the diagonal of the rectangle is 250 ft ...
