We Distribute, Yet Things MultiplyClass 8 Mathematics Assertion & Reason Questions

Assertion (A): The expansion of $(x+3)(y+5)$ is $xy + 5x + 3y + 15$.

Reason (R): The product of two binomials $(a+b)(c+d)$ is found by multiplying each term of the first binomial by each term of the second binomial, which results in $ac+ad+bc+bd$.

Assertion (A): The expansion of $(5m+6n)^2$ is $25m^2 + 36n^2$.

Reason (R): The identity for the square of a sum is $(a+b)^2 = a^2 + 2ab + b^2$.

Assertion (A): The value of $98 \times 102$ is $9996$.

Reason (R): The product can be calculated using the identity $(a-b)(a+b) = a^2 - b^2$, by setting $a=100$ and $b=2$.
