Students have to pick the correct option and check the answer provided here.1) x2-2x+1 is a polynomial in:a. One Variableb. Two Variablesc. Three variabled. None of the aboveAnswer: aExplanation: x2-2x+1 can be written as x2-2x1+1x0. Hence, we can see that x is the only variable having powers as whole numbers: 2,1 and 0.2) The coefficient of x2 in 3x3+2x2-x+1 is:a. 1b. 2c. 3d. -1Answer: bExplanation: The coefficient of x2 in equation 3x3+2x2-x+1 is the multiple of x2.3) A binomial of degree 20 in the following is:a. 20x + 1b. x/20 + 1c. x20 +1d. x2+20Answer: cExplanation: A polynomial having two terms and the highest degree 20 is called a binomial of degree 20.4) The degree of 4x3-12x2+3x+9 isa. 0b. 1c. 2d. 3Answer: dExplanation: The degree is the highest power of a variable in an equation.5) x2 – x is ________ polynomial.a. Linearb. Quadraticc. Cubicd. None of the aboveAnswer: bExplanation: A polynomial of degree two is known as a quadratic polynomial.6) x – x3 is a ________ polynomial.a. Linearb. Quadraticc. Cubicd. None of the aboveAnswer: cExplanation: A polynomial of degree three is known as a cubic polynomial.7) 1+3x is a _________ polynomial.a. Linearb. Quadraticc. Cubicd. None of the aboveAnswer: aExplanation: A polynomial of degree one is known as a linear polynomial.8) The value of f(x) = 5x−4x2+3 when x = -1, is:a. 3b. -12c. -6d. 6Answer: cExplanation: When x= -1f(x)=5x−4x2+3f(−1)=5(−1) −4(−1)2+3=−5–4+3=−69) The value of p(t) = 2+t+2t2−t3 when t=0 isa. 2b. 1c. 4d. 0Answer: aExplanation: p(0)=2+0+2(0)2–(0)3=210) The zero of the polynomial f(x) = 2x+7 isa. 2/7b. -2/7c. 7/2d. -7/2Answer: dExplanation: f(x)=2x+7⇒2x+7=0⇒2x=−7⇒x=−7/2∴x = −7/2 is a zero polynomial of the polynomial f(x).
