PTDTTNT:
1. x^2-x-12
2. x^3-y^3-3x^2+3x-1
3. x^2-3xy+2y^2
4. 4X^3-5x^2-16x+20
PTDTTNT
x^20+x+1
(x^2+y^2+1)^4-17(x^2+y^2+1)x^2+16x^4
PTDTTNT
`x^2-5x+5y-y^2`
các bạn giai giup mk gap nhé. Thank you!!
PTDTTNT bang cach nham nghiem C= 6x^4-x^3-7^2+x+1
D= (x2-5x)2+10(x2-5x)+24
1/tìm x biết
(X2-2x+1):(x-1)+5x=8
2/PTDTTNT
x2-y2-5x+5y
16x -5x mũ 2 -3
16x-5x^2-3
a) 2x3 + 3x - 5
b) 16x - 5x2 - 3
c) x2 + 4x + 3
d) x2 - 4x - 5
e) 16x - 5x2 - 3
