The like terms in 3x (3 - 2y) and 2 (xy + x²) are
(a) 9x and 2x²
(b) -6xy and 2xy
(c) 9x and 2xy
(d) -6xy and 2x²
Solution:
Given, the expressions are 3x (3 - 2y) and 2 (xy + x²).
We have to find the like terms.
The terms having the same algebraic factors are called like terms.
3x (3 - 2y) = 3x(3) - 3x(2y)
= 9x - 6xy ----------------------------- (1)
2 (xy + x²) = 2(xy) + 2(x²)
= 2xy + 2x² --------------------------- (2)
From (1) and (2),
Terms having same algebraic factors = -6xy and 2xy
Therefore, the like terms are -6xy and 2xy.
✦ Try This: The like terms in 2x (2 + 6y) and 5 (xy + 3x²) are
(a) 4x and 6x²
(b) 12xy and 5xy
(c) 4x and 6xy
(d) -3xy and 4x²
