Q1. The value of the polynomial P(x) = 5x³ – 3x² + 7x – 10,when x = -1 is:

(a) 7     (b) 17       (c) -18      (d) -25

Ans. The given polynomial P(x) =5x³ – 3x² + 7x – 10

The value of the polynomial when x =-1

P(-1) = 5(-1)³ -3(-1)² +7(-1) -10 = -5 -3 -7 -10 =-25

Q2.One of the  zeroes of the polynomial P(x) = x² – 1 are :

(a) -1       (b) -2       (c) 0      (d) -3

Ans. (a) -1

The given polynomial is P(x) = x² – 1

P(x) = x² – 1 = 0

(x +1)(x -1) = 0

x = -1 and x = 1

Q3.The product of ( x + 1/x)(x -1/x)(x² + 1/x²) is :

(a) (x – 1/x)³       (b) x  + 1/x³       (c)  x4-1/ x4    (d)  x4+ 1/ x4

Ans. The given expression is

(x + 1/x)(x -1/x)(x² + 1/x²)

= (x² – 1/x²)(x²+1/x²) [i.e a² -b² = (a +b)(a – b)]

= ( x4-1/ x4) [ i.e a² – b² = (a + b)( a – b)]

Q4.If  x/y  + y/x = -1 (x,y ≠ 0), then the value of x³ – y³ is

(a) 1  (b) (x -y)(x² – y² +1)     (c) 0   (d) -1/2

Ans.(c) 0

The given equation is

x/y + y/x = -1

(x² + y²)/xy = -1

x² + y² = -xy….(i)

Cubing both sides

The value of x³ – y³ = (x -y)(x² +y² + xy)

Putting the value from equation (i)

x³ – y³ = ( x – y)( -xy +xy) =0

Q5. The value of 625² – 575²  is

(a) 50000         (b)30000           (c)60000            (d) 40000

Ans.

625² – 575² = (625 + 575)(625 – 575) = 1200 × 50 =60000

Q6. If x² + kx + 6 = ( x +1)( x – 3),then value of k is

(a) 1            (b) -1          (c) 2          (d) -1

Ans. The given equation is

x² + kx + 6 = (x +2)( x +3)

x² + kx + 6 = x² + (2+3)x + 2×3 = x² + 5x +6

On comparing LHS and RHS

k = 5

Q7. The coefficient of x³ in ( 2x² + 2x)(5x³ – 9x²) is:

(a) -15       (b) -18       (c) 27        (d) -28

Ans. (2x² + 2x)(5x³ -9x²) for getting the coefficient of x³,multiplying 2x and -9x² i.e 2x×-9x² = -18x³

Hence the coefficient of x³ is -18

Q8. Find the remainder when the polynomial 3x³ – 8x² + 17x + 4 is divided by x:

(a) 2        (b) -4         (c) 4        (d) 0

Ans.(c) 4

The given polynomial is 3x³ – 8x² + 17x + 4

Putting the value x = 0

3(0)³ – 8(0)² +17(0) + 4 = 4

Q9.If 2x + y + 3z = 0, then the value of  8x³ + y³ + 27z³ is :

(a) 18xyz        (b) -18xyz        (c) 36xyz        (d) -36xyz

Ans.(a) 18xyz

The given equation is

2x + y + 3x = 0

Applying the identity

a³ + b³ +c³ – 3abc = (a + b +c)(a² + b² + c² – ab – bc -ac)

(2x)³ + y³ + (3z)³ – 3×2x×3z = ( 2x + y +3z)(4x² + y² + 9z² -2xy – 3yz – 6xz)

Putting the value of 2x + y +3z = 0

8x³ + y³ + 27z³ = 0

Q10. If area of the rectangle is 4x² + 4x – 3,then its possible diensions are :

(a) 2x +1, 2x +3    (b) 3x -1, 2x +1    (c) 2x -3,2x +5     (d) 2x +3,2x -1

Ans.

4x² + 4x – 3

=4x² + 6x – 2x – 3

=2x( 2x + 3) -1(2x + 3)

=(2x + 3)(2x – 1)
