Question

evaluate. the following products algabric expressions class 8 and how to solve these sums

Answer 1

this may be the answer check it out

Answer 2

1. (x^2 + 3) (x^2 + 4)

= (x^4 + 4x^2 + 3x^2 + 12)

= x^4 + 7x^2 + 12.

Suppose The elements are (a^2 + b) (c^2 + d), where b and d are integers,

Then the product will be like

first element of bracket 1 with first element of bracket 2

then first element of bracket 1 with second element of bracket 2

then second element of bracket 1 to first element of bracket 2

then second element of bracket 1 to second element of bracket 2

( while multiplying negative sign will dominate)
