p=2x mũ 2+1 + x mũ 4 -5x Q= x mũ 4 +5 - 3 mũ 2 =5x a. Tính tổng A(x)= P+Q b. chứng minh rằng A(x) không có nghiệm

The linear equation is: y=ax+b

step-by-step explanation:

when the line is solid:

it's either < or >

when the line is dashed:

it's either < or >

this > inequality sign means:

this < inequality sign means:

this < inequality sign means:

about the problem:

since the line is solid, that means it's either < or >

srry i'm not done ! i'll

The answe maybbe

Looks pretty good to me!
