Question

Use FOIL to explain how to find the product of (a + b)(a − b). Then describe a shortcut that you could use to get this product without using FOIL.

Answer 1

⭐Solution⭐

✏given here

(a+b)(a-b)

= a²-ab +ba -b²

= a² - b²

✏By short cut multiplications by using identity .

✒identity will be here .

♠ (x+y)(x-y)= x² - y²

✏So, will be these product ,

(a+b)(a-b)

= a² - b²
