Mang jose wants to make a table which has an area of 8 m^2. The length of the table has to be 2 m longer than the width.
1. if the width of the table is p meters what will be its length?
2.form a quadratic equation that represents the situation?
3.find the solution from the given quadratic equation?
4.give the dimension of the table?
what is 2 more than p ?
isn't it p+2 ?
area = p(p+2)
p^2 + 2p = 8
p^2 + 2p - 8 = 0
which factors to
(p+4)(p-2) = 0
p = -4, which is not admissable
p = 2
so the table is 2 m by 4 m
check: what is 2 x 4 ?
