Question

The area of a rectangular garden is given by the trinomial x^2+x-30. What are the possible dimensions of the rectangle? Use factoring.
A)(x-6) and (x-5)*
B)(x+6) and (x-5)
C)(x+6) and (x+5)
B)(x-6) and (x+5)

Answer 1

When I expand your choice of answer, I get
x^2 - 11x + 30, so clearly not the right answer.

you can tell from the -30, that the two constants must be of opposite sign, ruling out A and C
Try expanding the other two

Answer 2

Its C @Reiny

Answer 3

No, Evan, I thought we had ruled out C

Did you expand C before you decided?

for C: (x+6)(x+5)
= x^2 + 5x + 6x + 30
= x^2 + 11x + 30, not the given expression

for B:
(x+6)(x-5)
= x^2 - 5x + 6x - 30
= x^2 + x - 30 , the given!!

Answer 4

ohhh so its B @Reiny
