1). Make corrections to Problem 3.3 and 3 ACE 18-20. Be prepared for a quiz on Monday.
2). Complete Problem 3.4
Remember, once you have the quadratic equation set up in factored form, make each quantity equal to zero to solve for x.

i don't really understand how to do problem B in 3.4
it's hard for me to find out what x is
Did you take notes on Friday? You need to first have each equation in factored form, like in B1. Then you need to set each quantity equal to zero. So using B1 as the example, x + 1 = 0. Solving for x, x would be equal to negative one. Likewise, setting 2x + 7 = 0 would result with x equal to a negative 7/2.
Once again, write each quadratic in factored form, set each quantity equal to zero, and solve for x.
