The value of (2x² + 4) ÷ 2 is
(a) 2x² + 2
(b) x² + 2
(c) x² + 4
(d) 2x² + 4

Solution:

Correct option is (b).

Given, (2x² + 4) ÷ 2

On dividing the polynomials, we get

= 2(x² + 2) ÷ 2

Canceling common term,

= (x² + 2)

✦ Try This: The value of (5x²y + 10x) ÷ 5x is (a) xy + 2, (b) x + 2, (c) y + 2, (d) xy - 2

Option is (a)

(5x²y + 10x) ÷ 5x

= 5x(xy + 2) ÷ 5x

= xy + 2
