1.If polynomial 2 -3x+ has zeros a.B, then form a polynomial having zeros 3a,3B.If the product of zeros of ar-60-6 is 4, then find the sum of zeros.2.Obtain all the zeros of '-177-36x-20 if two of its zeros are 5 and -2.if 2 and 3 are zeros of polynomial r'+(a+1)x+b, then find the value of a and b.If the qu. equation (a-b)x+(6-c)x+(c-a)=0 has equal roots then show that 2a = b + c3.Solve for x :-98-9(a+b)x+(2a + 5ab + 26 ) = 0 by factorisation and quadratic formullaFind x.: -1-5 aCost of certain length of a piece of cloth is Rs. 200. if the iece was 5m longer and each meter of clothcosts Rs. 2 less, the cost of the piece would have remain unchanged. How long is the piece?A SABC, it Ld at C. If P is the length of the perpendiculer from C to AB and a,b,c are lengths ofsides opposite to LA.ZB.ZC respectively, then prove that |
