Answer:

#x=1/3,x=3#

Explanation:

#"factorise the quadratic by 'splitting' the x-term"#

#rArr3x^2-10x+3=0#

#rArr3x^2-9x-x+3=0#

#rArr3x(x-3)-1(x-3)=0#

#rArr(x-3)(3x-1)=0#

#rArrx=3,x=1/3" are the zeros"#

Answer:

Zeros are #x=3 and x=1/3#

Explanation:

#3x^2-10x+3=0 or 3x^2-9x-x+3=0 or 3x(x-3)-1(x-3)=0 # or

#(x-3)(3x-1)= 0 :.# either

# x-3=0 :. x=3 or 3x-1=0 :. 3x=1 :. x=1/3#

Zeros are #x=3 and x=1/3# [Ans]
