1.	If one zero of apolynomial x2+bx+c is-273 then the value ofcis.
Answer» Let m and n are zeroes of x^2 + bx + c = 0 Given,m = - 2 root(3) Sum of zeroes = cm + n = - b-2root(3) + n = - bn = 2root(3) - b...... (1) Product of zeros = cmn = c-2root(3)n = c.......(2) Put value of n from eq(1) in eq(2), we get-2root(3)[2root(3) - b] = cc = - 43 + 2b root(3)c = 2b root(3) + 12

Answer»

Let m and n are zeroes of x^2 + bx + c = 0

Given,m = - 2 root(3)

Sum of zeroes = cm + n = - b-2root(3) + n = - bn = 2root(3) - b...... (1)

Product of zeros = cm*n = c-2root(3)*n = c.......(2)

Put value of n from eq(1) in eq(2), we get-2root(3)*[2root(3) - b] = cc = - 4*3 + 2b root(3)c = 2b root(3) + 12
