`3(x-1)(x-5) =0`
`<=> (x-1) =0` hoặc `x-5 = 0`.
`<=> x =1` hoặc `x = 5`.
Vậy `x = 1` hoặc `x = 5.`
`b, 3x^2 + 7x = 10`.
`<=> 3x^2 + 7x - 10 = 0`
`<=> (3x+10)(x-1) =0`
`<=> 3x + 10 = 0` hoặc `x - 1=0`
`<=> x = -10/3` hoặc `x = 1.`
Vậy `x = -10/3` hoặc `x = 1.`
bài 1 tìm x
a)3x(x-3)+4x-12=0
b)(x+1)(x^2-x+1)-x^3+2x-=17
c)(x-3)(x+5)+(x-1)^2-6x^4y^2:3x^2y^2=15x
giúp mik vs nhanh ak cảm ơn nhìu!
