Which polynomial can transform $7ab+8b^2+7$ into $9 a^2+ ab + 3$ by only using the addition operator?
Given:
The first polynomial is $7ab+8b^2+7$ and the second polynomial is $9 a^2+ ab + 3$.
To do:
We have to find the polynomial that can transform $7ab+8b^2+7$ into $9 a^2+ ab + 3$ by only using the addition operator.
Solution:
Let the polynomial that has to be added to $7ab+8b^2+7$ to transform it into $9 a^2+ ab + 3$ be $x$.
This implies,
$(7ab+8b^2+7)+x=9 a^2+ ab + 3$
$x=9a^2+ab+3-(7ab+8b^2+7)$
$x=9a^2-8b^2+ab-7ab+3-7$
$x=9a^2-8b^2-6ab-4$
The required polynomial is $9a^2-8b^2-6ab-4$.
