Question

The given expression '2x²+3y+5z²+10p+6y+7x^2', on simplification gives:

Options:

A . 9x2+9y+5z2+10p

B . 11x2+2y+10z2+10p

C . 9x2+12y+5z2+10p

D . 19x2+10y+5z2+10p

Answer: Option A
:
A
Given expression is
2x²+3y+5z² +10p+6y+7x²
Group the like terms:
= (2x²+7x²) + (3y+6y) + 10p + 5z²
Solve groups:
=x²(2+7)+y(3+6)+5z²+10p
=9x²+9y+5z²+10p
