xac dinh cac he so a,b,c biet rang:
ax^3+5x^2-4x+2=4x^3- (b-2)x^2+cx+ (d-3)
xac dinh cac he so a,b,c biet rang:
ax\(^3\)+5x\(^2\)-4x+2=4x\(^3\)-(b-2)x\(^2\)+cx+(d-3)
xac dinh cac he so a,b,c biet rang:
ax\(^3\)+5x\(^2\)-4x+2=4x\(^3\)-(b-2).x\(^2\)+cx+(d-3)
xac dinh cac he so a,b,c biet rang:
ax\(^3\)+5x\(^2\)-4x+2=4x\(^3\)-(b-2)x\(^2\)+cx+(d-3)
xac dinh cac he so a,b,c biet rang:

xac dinh a,b,c biet rang:
2x^2-3x-4=ax^2+bx-(c+1)
ax^3+5x^2-4x+2=4x^3-(b-2)x^2+cx+(d-3)
A=1/3(xy^2)^2. (1/2x^2y)^2.4/5x^3
B=2x^4y.1/4x^2y^2.(-2xy)^3
Thu gon da thuc tren
Xac dinh he so ,bac cua cac don thuc vua thu gon
Tinh A+B va A-B
A=1/3(xy^2)^2.(1/2x^2y)^2.4/5.x^3
B=-2x^4y.1/4x^2.y^2.(-2xy)^3
Thu gon da thuc tren
Xac dinh he so ,bac cua cac don thuc vua thu gon
Tinh A+B va A-B
a) Xac dinh he so m de da thuc A(x) = mx2_2x co nghiem la 3
b) Chung to da thuc sau khong co nghiem
B(x) = x2+4x+10
