Question

Which polynomial identity will prove that 49 - 4 = 45?

Answer 1

Answer choices:

Answer 2

as is clear on your equation, 49 is a square given by 7x7
as is clear in your equation, 4 is a square given by 4x4

the operator given is - ( minus)

you have two squares, and a difference sign

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

7^2 -2^2 = (7-2)(7+2)
= (5)(9)
= 45

it is the diffeernce of two squares

Answer 3

Thank you friend :D
