Question
$a^2- b^2= (a + b )$ __________.
✓
Answer
$a^2- b^2= (a + b ) (a - b).$
Solution:
We have, $a^2- b^2= (a + b)(a - b)$
Alternative Answer:
Let $(\text{a}^2-\text{b}^2)=(\text{a}+\text{b})\text{x}$$\text{x}=\frac{\text{a}^2-\text{b}^2}{\text{a}+\text{b}}$
$=\frac{(\text{a}+\text{b})(\text{a}-\text{b})}{\text{a}+\text{b}}=\text{a}-\text{b}$
Solution:
We have, $a^2- b^2= (a + b)(a - b)$
Alternative Answer:
Let $(\text{a}^2-\text{b}^2)=(\text{a}+\text{b})\text{x}$$\text{x}=\frac{\text{a}^2-\text{b}^2}{\text{a}+\text{b}}$
$=\frac{(\text{a}+\text{b})(\text{a}-\text{b})}{\text{a}+\text{b}}=\text{a}-\text{b}$
