1.	if α and β are the zeroes of the polynomial x^2 + 7x + 12 then find the value of α+β+2αβ
Answer» Since alpha and beta are zeros of the following polynomial therefore alpha + beta + 2 alpha beta is equals to alpha + beta whole square replacing alpha + beta by minus b Upon a now we have given the value of b and a we will put in this and we get answer 49 17 -7+2×12=17 Sorry 17 1.Identify a,b,c values from given quadratic equation 2.find sum of zeros and product of zeros 3.Substitute in the given expression Then we will get answer as 14
