Question

find zeros of following-
3x+5+2x-8
x²-5x+6
3x²+5x+2
x⁴-136x²+3600
x³-6x²+11x-6​

Answer 1

Answer:(i) p(x) = x³ – 3x² + 5x – 3, g(x) = x² – 2 q(x) = x - 3, r(x) = 7x - 9 Verification : p(x) = g(x) x q(x) + r(x) = (x² – 2)(x - 3) + 7x - 9 = x³ – 3x² - 2x + 6 + 7x – 9 = x³ – 3x² + 5x – 3 ... + r(x) = (x² + 1 – x )(x² + x - 3) + 8 = x⁴ + x³ – 3x² + x² + x - 3 - x³ - x² + 3x + 8 = x⁴ – 3x² + 4x + 5 ... (ii) x² + 3x + 1, 3x⁴ + 5x³ – 7x² + 2x + 2 The remainder is 0.
