Question

The area of a rectangular garden is given by the trinomial x^2 + 6x – 27. What are the possible dimensions of the rectangle? Use factoring.

Answer 1

x^2+6x=27
x(x+6)=27
x=3 or x=9

Answer 2

wait ignore the last line

Answer 3

x^2+6x=27
x(x+6)=27
x = 3
so one side could be 3, the other could be 9.

Answer 4

x^2+6x+27=0
x^2+3x+9x+27=0
x(x+3)+9(x+3)=0
x+3=0 or x+9=0
x=-3 x=-9

Answer 5

it was -27 StAr

Answer 6

Woops sorry !

Answer 7

x^2+6x-27=0
x^2-3x+9x-27=0
x(x-3)+9(x-3)=0
x-3=0 or x+9=0
x=3 x=-9

Answer 8
