Since the discriminant is −3, there are no real solutions. If you are allowed to use complex numbers, you'll see that √−3 = i√3, and so the two conjugated solutions are x1 = − 1 2 +i √3 2, and x2 = − 1 2 −i √3 2. You can use the standard formula which allows you to solve any quadratic equation, which is x_ {1,2} = \frac {-b ...

Có thể trong đó có câu trả lời mà bạn cần!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 ...

Solution. The function f (x) = 1 u2 +u−2 suffers a discontinuity at the points where u2 +u−2 =0 i.e., u =−2 and u = 1. Using these value of u, the corresponding values of x are obtained by solving the equations. Hence, the composite function is discontinuous at three points x = 1 2,x = 1 and x = 2.
