1 The equation of two polynomials P(x)/Q(x) where Q(x) ≠ 0 with no common factor is called 12 1 10 -10
2 Partial fraction of 1/x3-1 will be of the form Conjugate pair ordered pair reciprocal pair quadratic function
3 A relation in which the equality is true only for some values of the unknown variable is called An identity An equation A polynomial Inverse function
4 A fraction in which the degree of the numerator is less than the degree of the denominator is called 1-i √-3 / 2 -1+i √-3 / 2i -1+i √3 / 2 1+i √3 / 2
5 1/x2 -1 = ? (in case of making partial fraction) Ax +B/x<sup>2</sup> -1 A/x + B/ x- 1 A/ x+1 + B/x-1 None
6 x2 +2x -25 = 0 is 1 2 3 4
7 (x+2)2 = x2 +4x +4 is 1 2 3 4
8 x-1/(x+2)(x-2) = 4/3(x-4) -1/3(x-1) 3/4(x+2) + 1/4(x-2) 2/3(x-2) - 4/3(x+2) 3/x - 2/x+1
9 2/(x+1)(x-1) = A/x+1 + B/x-1 corresponds to α = b/a and&nbsp;β = ca α = a/b and&nbsp;β = -c/a α<sup>2</sup> +&nbsp;β<sup>2</sup> = 1 α = -b/a and&nbsp;β= c/a
10 Which is a proper rational fraction 3x - 7/x<sup>2</sup> +4 2x<sup>2</sup> - 5/x<sup>2</sup> + 4 3x<sup>4</sup>/2x<sup>2</sup> - 15 All are proper rational fraction
