Question

Solve: 2017* 2017 - 2015 2015
4032
= How much? (Select two correct alternative​

Answer 1

Step-by-step explanation:

Given Solve: 2017 x 2017 - 2015 2015  / 4032  = How much? (Select two correct alternative s)

• Given 2017 x 2017 – 2015 x 2015 / 4032
• Now we can write this as (2017)^2 – (2015)^2 / 4032
• So this is in the form of a^2 – b^2 = (a + b)(a – b)
•                                                      = (2017 + 2015)(2017 – 2015) / 4032
•                                                    = 4032 x 2 / 4032
•                                                    = 2

Therefore the correct alternatives will be 2 and √4

Answer 2

Answer:

2 and √4

Step-by-step explanation:

2017 * 2017 - 2015 * 2015 / 4032

(2017)² - (2015)² /4032

$a { }^{2} \: - \: b {}^{2} =(a + b)(a - b)$

,,is the formula for numerator of our equation..

(2017 + 2015)(2017 - 2015) / 4032.

4032 * 2 / 4032

1 * 2

= 2 or √4
