1.	No. of terms in the product of a binomial and a trinomial are ………………… A) 10B) 9 C) 6 D) 7
Answer» Correct option is C) 6 Correct option is (C) 6 Let \(ax_1+bx_2\) is a binomial and \(cy_1+dy_2+ey_3\) is a trinomial. Then their product \(=(ax_1+bx_2)\) \((cy_1+dy_2+ey_3)\) \(=acx_1y_1+adx_1y_2+aex_1y_3\) \(+bcx_2y_1+bdx_2y_2+bex_2y_3\) \(\therefore\) No. of terms in the product = 6.

Answer»

Correct option is C) 6

Correct option is (C) 6

Let \(ax_1+bx_2\) is a binomial and \(cy_1+dy_2+ey_3\) is a trinomial.

Then their product \(=(ax_1+bx_2)\) \((cy_1+dy_2+ey_3)\) \(=acx_1y_1+adx_1y_2+aex_1y_3\) \(+bcx_2y_1+bdx_2y_2+bex_2y_3\)

\(\therefore\) No. of terms in the product = 6.
