Question

What is the formula for a2-b2

Answer 1

Answer:

required formula is (a+b)(a-b)

Answer 2

Answer:

Formula of $a^2 -b^2$ = (a +b)(a - b)

Step-by-step explanation:

Explanation:

$a^2 - b^2 = (a +b)(a-b)$

Examples on $a^2 - b^2$  Formula,

Let us assume that a = 100 and b = 6.

We will substitute these in the $a^2 - b^2$ formula.

⇒ (100 + 6) (100 - 6)= 106 × 94 = 9964

Let us another example:

Factorize the expression 25$x^2$ - 64.

So , this can be written as,

⇒$25x^2 - 64$

⇒$(5x)^2 - (8)^2$

Now from the formula, $a^2 - b^2 = (a +b)(a -b)$

⇒(5x + 8)(5x - 8)

Final answer:

Hence, formula of $a^2 - b^2 = (a +b)(a - b)$.
