16:36 Real Motivation We can't forget about the contribution of "x" in algebra....
Synthetic division is also a useful approach to solve the questions explained in the start using remainder theorem .
Love your way of explanation, Thanks to the entire careerride team especially u mam🥰🥰
madam in the 1st q 4(-4)cube will be -256 but you write it -128

The Wrong Answer At the video time 7:34, while doing this problem, she got it wrong. The problem was (4x^3+13x^2-5x+1). Her answer was 101. The problem’s actual answer was -27. The last bracket problem was: (-256+208+20+1). Instead of putting in -256, she took half of it, and wrote -128.

maam in eg 15a i think it would be x^2+1/x^2 -2 insted of +2 so the ans would be 25+2 =27 please confirm

Is the question at 32:49 wrong? Because taking x = 0 and y = 0 gives different answers
55:20 ma'am you forgot to square the other side of the equation (The answer of the question will be 9 I have used a different method)

With q.16 1:05:00 , how did you get 54 root 2, isn't it supposed to be 27 root 2, don't we have to cube the square root as well?
@Misoraaa_
Жыл бұрын
I guess they are considering root2 cube as root2 x square of root2 then sq of root2 = 2 and then multiply it with 27 we will get 54 and write that root2 as it is... I don't know what logic I've applied but that's how only it can come 54 root2 I guess...

you can take 5powX common -> 5powX - 5powX-1 = 5powX+1 - 5powX = 5powX * (5-1) ma'am took 5powX-1 as common, both way is correct.

For any equation, if you change one variable, the other will also change accordingly to keep the balance but the balance would stay for the equation to exist. .

How come 4(_4)^3 become 128. You also make me confused regarding the changes in symbol(_,+).In some case,_.(_) turn '+' but in other it's the opposite.
