Question

Find the product (Ix? + 11y)(x - y) and verify the result for x = 2 and y = 1​

Answer 1

Answer:

sorry don't know this answer

Answer 2

Answer:

21y2-11y-2=0

21y2-14y+3y-2=0

7y(3y-2)+1(3y-2)=0

(7y+1)(3y-2)=0

y=-1/7 and y = 2/3

a=7 b=-11/3 c=-2/3

sum of roots is -1/7+2/3=11/21 =-b/a

product of root=-2/21=c/a
