Question

alpha,beta are the zeroes of x²+3x+4 then find the value of alpha²+beta²​

Answer 1

Answer:1

Step-by-step explanation:

alpha beta are the roots of the given equation

Let alpha be m

Let beta be n

Then m^2+n^2=(m+n)^2-2mn

Sum of roots = -b/a=-3/1=-3 for the general equation ax^2+bx+c=0

Product of roots = c/a=4/1=4

=(-3)^2-2(4)=9-8=1
