Question

find the value of x. 1/4 x + 1/6 x = 1/2 x + 3/4​

Answer 1

Step-by-step explanation:

$.$

Let x + 1 = a and x − 1 = b

We notice that 1, 4, 6, 4, 1 are the values of 4C0, 4C1, 4C2, 4C3, 4C4 respectively and

∴ the given expression becomes

4C0a4b0 − 4C1a3b + 4C2a2b2 − 4C3ab3 + 4C4a0b4

= (a − b)4

= [x + 1 − (x − 1)]4

= (x + 1 − x + 1)4

= 24

= 16
