Question 94270
A square has sides of length 3x -2 cm. Express the area of the square as a polynomial.


The side of the square here = 3x-2cm

Area of the square = side *side

Area of the square = (3x-2)(3x-2)cm^2

                   = (3x-2)^2cm^2

This is of the form (a-b)^2 = a^2-2ab +b^2

Area of the square = 9x^2 - 12x +4square cm
