My question was; "A rectangle has sides of length x+3cm and 3x-2cm, given that the area of the rectangle is 104cm^2, find the value of x"
I started out by doing the formula A=L x W and done x+3(3x-2) and by the end got
12x^2-8x= 104 then I made in a quadratic by making it 12x^2-8x-104= .
I am very stuck so I am pretty certain I have made a mistake, would any one be able to find my mistake and explain the process, thank you!!
