Tap for more steps... x2 + (x+1)2 = x2 +4x+4 x 2 + ( x + 1) 2 = x 2 + 4 x + 4. Move all terms containing x x to the left side of the equation. Tap for more steps... x2 − 2x+1 = 4 x 2 - 2 x + 1 = 4. Subtract 4 4 from both sides of the equation. x2 − 2x+1−4 = 0 x 2 - 2 x + 1 - 4 = 0. Subtract 4 4 from 1 1. x2 − 2x−3 = 0 x 2 - 2 x - 3 = 0.

Example 2: Factorise (x 4 – 1) using standard algebraic identities. Solution: (x 4 – 1) is of the form Identity III where a = x 2 and b = 1. So we have, (x 4 – 1) = ((x 2) 2 – 1 2) = (x 2 + 1)(x 2 – 1) The factor (x 2 – 1) can be further factorised using the same Identity III where a = x and b = 1. So, (x 4 – 1) = (x 2 + 1)((x) 2 ...

To see that this is the only possible value of x +y, note that the function f (x) = x +√x2 + 1 is strictly monotonic increasing. So if x1 + √x2 1 + 1 = x2 +√x2 2 +1 then x1 = x2. Answer link.

Explanation: I usually make no attempt to remember the derivatives of inverse trig function and would have to look up the result. Therefore, Inverse trig functions are more easily differentiated by rewriting in terms of the non-inverse trig function and implicit differentiating. Let y = arctan(x)1 2. ∴ y = √arctanx. ∴ y2 = arctanx. ∴ ...Solution. Verified by Toppr. f (x) = x2 −x+1 x2 +x+1. f ′(x) = (x2 +x+1)(2x−1)−(x2 −x+1)(2x+1) (x2 +x+1)2 = 2(x2 −1) (x2 +x+1)2.
