Question 548715: "The sides of one square have a length 2ft more than the sides of another square. If the area of the larger square is subtracted from three times the area of the smaller square the result would be 12 sq. feet. Find the lengths of sides of the smaller square."
My equation: (x+2)(x+2)-3x^2= 12
x%5E2%2B4x%2B4-3x%5E2=12
-2x%5E2%2B4x-8=0
2x%5E2-4x%2B8=0
My problem is I plugged it into quadratic formula and only ended up with no real solutions. Please and Thank you.
