Question

For each of the following, evaluate
(i) (16r – 2s)^2– (16r + 2s)^2, ifr = -3, s = 6.​

Answer 1

Answer:

Here is ur answer mate...

(16r - 2s)² - (16r + 2s)²

On factorising...

(16r-2s+16r+2s)(16r-2s-16r-2s)

(32r)(-4s) -----------(i)

Given r = -3 and s = 6...

Putting it on eqn (i)

[32(-3)][-4(6)]

(-96)(-24)

2304 ans...
