Question

find value of x using identities
46x =68*68 - 45*45​

Answer 1

Step-by-step explanation:

46x=4628-2025

46x=2603

x=2603/46

x=56

Answer 2

Hey! it's easy!

Step-by-step explanation:

For this we can use $a^{2} - b^{2}$

So, 46 x =  $a^{2} - 2ab + b^{2}$

46 x = $68^{2} - 2 (68) (45) + 45 ^{2}$

46 x = 4624 - 6120 + 2025

46 x = 529

x = 11.5
