Write a quadratic equation whose roots are alpha + 1 and -(alpha+6)

answered-by-expert Expert Answer
Let roots are (α+1)  and -(α+6)
 
quadratic eqn :  x2 - (sum-of-roots)x + (product-of-roots) = 0
 
sum of roots = (α+1)-(α+6) =  -5
product of roots = -(α+6) (α+1) =
 
hence quadratic equation :   x2 +5x -(α+6) (α+1) = 0
