Hi iam V and iam a good boy

Answer 1

4)

1. 5×1/5=0,so x=1/5
2. a×-b/a+b=0,so y=-b/a
3. -4×-5/-4+5=0,so x =-5/-4
4. 3×-1/3+1=0,so y=-1/3

5)

1. 3×4/3-4=0,so x=4/3
2. 3×-4/3+4=0,so x=-4/3
3. 7×0=0,so x =0

6)

1. (x-1)(x-2)(x-3)(x-4),(x-1)=0,x=1,(x-2)=0,x=2,(x-3)=0,x=3,(x-4)=0,x=4,x=1,2,3,4
2. f(1)=1^2-4×1+6=3

f(-1)=-1^2-4×-1+6=11

f(1)-f(-1)=3-11=-8

it may help u❤️❤️❤️
