If we subtract -3x²y² from x²y², then we get (a) - 4x²y² (b) - 2x²y² (c) 2x²y² (d) 4x²y²

Solution:

Correct option is (d) because, subtracting the polynomials, we get

x²y² - (-3x²y²) = x²y² + 3x²y² = 4x²y²

✦ Try This: If we subtract, -4xy from 12xy, then we get (a) - 16xy, (b) 16xy, (c) 8xy, (d) -8xy

Correct option is (b)

12xy - (-4xy) = 12xy + 4xy = 16xy
