Question

x²(3x-2x+x²) where x =2/3​

Answer 1

4/9(2-4/3+4/9)

4/9(22/9-4/3)

4/9(10/9)

40/81

hope it helps you

Answer 2

           X^2(3X-2X+X^2)

          = (2/3)^2{3(2/3)-2(2/3)+(2/3)^2}

          =(4/9){(2)-(4/3)+(4/9)}

          = (4/9){(18-12+4)/9}

          = (4/9) (10/9)

          = 40/81

(Ans): 40/81
