If P(x) = x³ − 2x² + 5x + 1, then find P(1):
Answer: B. 5
P(1) = 1 − 2 + 5 + 1 = 5.
Complete solution of |x| = 3 is:
Answer: C. ±3
|x| = 3 gives x = 3 or x = −3.
An equation that can be written in the form ax + b = 0, (a ≠ 0) where a and b are constants and x is a variable, is called:
Answer: B. Linear equation
ax + b = 0 is a linear equation.
Factorization of x⁴ − 16 is:
Answer: D. (x−2)(x+2)(x²+4)
x⁴ − 16 = (x² − 4)(x² + 4) = (x−2)(x+2)(x²+4).
Factorization of a² − 1 is:
Answer: A. (a−1)(a+1)
Difference of squares.
An algebraic expression of the form P(x)/Q(x), Q(x) ≠ 0 and P(x), Q(x) are polynomials is called:
Answer: B. Rational expression
A ratio of two polynomials (denominator non-zero) is a rational expression.
Simplify: [x(2x − 1)²/(2x² − 1)] ÷ [(4x² − 1)/(4x² + 4x + 1)]
4x² − 1 = (2x − 1)(2x + 1) and 4x² + 4x + 1 = (2x + 1)².
= [x(2x − 1)²/(2x² − 1)] × [(2x + 1)²/((2x − 1)(2x + 1))]
= x(2x − 1)(2x + 1)/(2x² − 1).
If B = 3x² + 14x + 8, H = 3x + 2, L = 6x³ + 25x² + 2x − 8, find A (polynomial). (Take H as H.C.F. and L as L.C.M. of A and B, so A × B = H × L.)
B = (3x + 2)(x + 4). From A × B = H × L: A = H·L/B = (3x + 2)·L/[(3x + 2)(x + 4)] = L/(x + 4).
(6x³ + 25x² + 2x − 8) ÷ (x + 4) = 6x² + x − 2.
A = 6x² + x − 2 = (3x + 2)(2x − 1).
