Question

Write x²-y² in factorize form.
write (p+p) ²in expanded form. ​

Answer 1

see explanation

Explanation:

x² - y² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

x² - y²

= (x - y)(x + y)

------------------------------

(p + p)²

= (2p)²

= 2p × 2p

= 4p²

Answer 2

(x-y)^2

p^2+p^2

Explanation:

^2 means square
