Question 1. Find the value of the polynomial 5x – 4x2 + 3 at (i) x = 0 (ii) x = – 1 (iii) x = 2 Solution: 1et p(x) = 5x – 4x2 + 3 (i) p(0) = 5(0) – 4(0)2 + 3 = 0 – 0 + 3 = 3 Thus, the value of 5x – 4x2 + 3 at x = 0 is 3. (ii) p(-1) = 5(-1) – 4(-1)2 + 3 = – 5x – 4x2 + 3 = -9 + 3 = -6 Thus, the value of 5x – 4x2 + 3 at x = -1 is -6. (iii) p(2) = 5(2)...
Question 1. Find the remainder when x3 + 3x2 + 3x + 1 is divided by (i) x + 1 (ii) x – (iii) x (iv) x + π (v) 5 + 2x Solution: Let p(x) = x3 + 3x2 + 3x +1 (i) The zero of x + 1 is -1. ∴ p(-1) = (-1)3 + 3(-1)2 + 3(-1) +1 = -1 + 3- 3 + 1 = 0 Thus, the required remainder = 0 (ii) The zero of is Thus, the required remainder = (iii) The zero of x is 0. ...
Question 1. Determine which of the following polynomials has (x +1) a factor. (i) x3+x2+x +1 (ii) x4 + x3 + x2 + x + 1 (iii) x4 + 3x3 + 3x2 + x + 1 (iv) x3 – x2 – (2 +√2 )x + √2 Solution: The zero of x + 1 is -1. (i) Let p (x) = x3 + x2 + x + 1 ∴ p (-1) = (-1)3 + (-1)2 + (-1) + 1 . = -1 + 1 – 1 + 1 ⇒ p (- 1) = 0 So, (x+ 1) is a factor of x3 + x2+ x...
Question 1. Use suitable identities to find the following products (i) (x + 4)(x + 10) (ii) (x+8) (x -10) (iii) (3x + 4) (3x – 5) (iv) (y2+ ) (y2– ) (v) (3 – 2x) (3 + 2x) Solution: (i) We have, (x+ 4) (x + 10) Using identity, (x+ a) (x+ b) = x2 + (a + b) x+ ab. We have, (x + 4) (x + 10) = x2+(4 + 10) x + (4 x 10) = x2+ 14x+40 (ii) We have, (x+ 8) (...
