Thanks! Will do!

You're welcome!

Mujhe bhi batana please last step smjh nahin aaya 😢

You should share an example. It helps. That would be Linear Algebra

@@PrimeNewtons ok sir

You can actually do that what i did : >k^2 + k^2 | Take out k^2 = k x k > k^2 + k *k | k*k = 5k because K>=5 > k^2 + 5k | split into 2k + 3k >k^2 + 2k + 3k | 3k>1 > k^2 + 2k + 1

so technically you're not wrong actually

Sir please improve on your board I can't see

U need to ask yourself what you don’t get: is it the principle of induction? The principle of calculating the inequality or maybe something simpler like the calculation rules ( I know you probably didn’t need this but once u break down what u undertaken and what u don’t it becomes much easier for you to help itself understand)

Please answer me.I feel so frustrating with inequalities induction. There are so many ways and I am dizzy now.

Why do u choose 4k which is not 5k? Why do u want to reduce?

Explain me please.

Is it normal to reduce and can I reduce almost every inequalities like that, sir?

Sir, will itbe wrong if I try to calculate =k square plus 5k =k square plus 2k plus 3k =ksquare plus 2k plus 1

Well basically that's the point. In mathematical induction for inequalities, as long it doesn't disrupt the thing which in this case, the greater than sign, you can basically make up ur own variables as long it makes the statement true. But not every variables, it only works when u try to proof it. By which in this example the 4k, because we know that k>4 which is essentially k=5, so sub it into the k^2, we get 25 right, then why it's 4k, because if we sub it into the 4(20), it's correct right 25>20 so there u go

U could say that it's 3k, just that remember to fact it out that it will become 2k + k for the next step, I don't think it works for 2k, it might work but there's gonna some explanation involved as well so just follow the variables from the (k+1)^2 expanded version
