The area of a square garden is represented by the quadratic expression 9x^2 - 12x + 4. The length of one side of the square garden is 91 inches. What is the value of x ?

Hint: Since the garden is in the shape of a square, the expression 9x^2 - 12x + 4 is the product of two identical factors. Factor the expression to find these identical factors. Each factor represents the length of one side of the square. Therefore, each factor equals 91. Once you make one of the factors equal to 91, you can solve for x.

I got (3x-2)(3x-2) but now i don't know what to after that so i can get the answer please.

  1. sure you do. Did you not read where it said

    Therefore, each factor equals 91?

    3x-2 = 91
    3x = 93
    x = 31

    It's hard to solve a problem if you don't read it!
