1 / 2 a - (2a-2 / 3 square) + (- 3 / 2 + 2 / 2 square), where a = - 2, B = 3 / 2 | Math enthusiast | Mathematical art

1 / 2 a - (2a-2 / 3 square) + (- 3 / 2 + 2 / 2 square), where a = - 2, B = 3 / 2

1 / 2 a - (2a-2 / 3 b) + (- 3 / 2 + 2 b)
=a/2-2a+2b²/3-3/2+2b²
=-3a/2+8b²/3-3/2
=-3/2*(-2)+8/3*(3/2)²-3/2
=3/2(-2+8/3*3/2-1)
=3/2*(-3+4)
=3/2
