State and prove remainder theorem and factor theorem |
| Answer» Remainder theorem: Let p(x) be any polynomial of degree greater than or equal to one and let a be any real number. If p(x) is divided by the linear polynomial x – a, then the remainder is p(a).Proof : Let p(x) be any polynomial with degree greater than or equal to 1. Supposethat when p(x) is divided by x – a, the quotient is q(x) and the remainder is r(x),i.e.,p(x) = (x – a) q(x) + r(x)Since the degree of x – a is 1 and the degree of r(x) is less than the degree of x – a,the degree of r(x) = 0. This means that r(x) is a constant, say r.So, for every value of x, r(x) = r.Therefore, p(x) = (x – a) q(x) + rIn particular, if x = a, this equation gives usp(a) = (a-a) q(a) + r = rwhich proves the theorem.Factor Theorem: \xa0x – a is a factor of the polynomial p(x), if p(a) = 0. Also, if x – a is a factor of p(x), then p(a) = 0, where a is any real number. This is an extension to remainder theorem where remainder is 0, i.e. p(a) = 0.Numerical: Examine whether x + 2 is a factor of p(x)= x3 + 3x2 + 5x + 6Solution : The zero of x + 2 is –2. As, per factor theorem, x+2 is factor of p(x) if p(-2) = 0.\xa0p(–2) = (–2)3 + 3(–2)2 + 5(–2) + 6 = 0.Thus, x+2 is factor of p(x)= x3 + 3x2 + 5x + 6 | |

Use euclids division algorithm to find hcf of 210 and 55 |
| Answer» HCF of 210 and 55Using Euclid\'s division algorithm.210 = (55*3) + 4555 = (45*1) + 1045 = (10*4) + 510 = (5*2) + 0So, the remainder is 0 at the last stage, so HCF of 210 and 55 is 5.\xa0∴ 5 = (210*5) + 55y⇒ 5 = 1050 + 55y⇒ - 55y = 1050 - 5⇒ - 55y = 1045⇒ y = - 1045/55⇒ y = - 19Hence, the value of x is 5 and y is - 19Ok this is the right answer .....?????? | |
