ai giup mik dc ko
tim x biết
a) 5x(x-3)+x-3=0
b) x4-4x3+4x2+0=0
ai giup minh vs
tim x biet
(3x+2)(2x+9)-(x+2)(6x+1)=x+1-(x-9)
TIM X BIET : (X+1)^2(X+2)+(X-1)^2(X-2)=12 .
GIUP MK NHA
Tim x, biet
x^3+6x^2+9x-x^4=0
giup minh giai bai toan nay nhe , minh like cho
tim x biet
a) 9x^2+6x+1=0
b) 25x^2=4
c) 8-125x^3=0
d) (2x+1)-10(2x+1)(x+2)+25(x+2)^2=0
GIÚP MIK VS NHÉ
TIM X BIET(X-2)^3-X^3+6X^2=7
tim x biet;(x-2)^3-x^3+6x^2=7
tim x,y,z biết
a)(2x-3)^2=0
b) 25x^2-10x+1=0
c) 6x+9=-x^2
d) 169-y^2=0
e) 2x^2-2xy-4x+5=0
giup mik vs
tôi đi hok
nhanh nhé
