Here's a step-by-step solution to each problem:
: Quadratic Equation Roots
Given: α−β=8 and α2+β2=74.
We need to find a quadratic equation with integer coefficients whose roots are r1=2α+β and r2=2β+α.
Step 1: Find αβ.
We know that (α−β)2=α2−2αβ+β2.
Substitute the given values:
82=74−2αβ
$64 = 74 -
