(x 2 + 1) 2 – x 2 = 0 has no real roots.. Explanation: Given equation is (x 2 + 1) 2 – x 2 = 0. ⇒ x 4 + 1 + 2x 2 – x 2 = 0 .....[∵ (a + b) 2 = a 2 + b 2 + 2ab]. ⇒ x 4 + x 2 + 1 = 0. Let x 2 = y. ∴ (x 2) 2 + x 2 + 1 = 0. y 2 + y + 1 = 0. On comparing with ay 2 + by + c = 0, we get. a = 1, b = 1 and c = 1. Discriminant, D = b 2 – 4ac = (1) 2 – 4(1)(1) = 1 – 4 = – 3.

⇒ x = (5 + 1) / 2. ⇒ 6 / 2 = 3. Thus, the solution of the given system of equations is x = 3 and y = 1. Important Notes on Solve for x. To solve for x (the unknown variable in the equation), apply arithmetic operations to isolate the variable. For solving 'x' number of equations we need exactly 'x' number of variables. Solve for x and y can be done by the …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.

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 ...

When a linear factor occurs multiple times in the factorization of a polynomial, that gives the related zero multiplicity. For example, in the polynomial f ( x) = ( x − 1) ( x − 4) 2 , the number 4 is a zero of multiplicity 2 . Notice that when we expand f ( x) , the factor ( x − 4) is written 2 times.Algebra Examples.
