Step-by-step explanation:
6 points would be the unit rate for one question.
Look at the last digit. If the last digit is 0, then the number can be divided by 10 <span> evenly (without a remainder).</span>
6(x²-4x+4-4)+1=0, 6(x-2)²-24+1=0, 6(x-2)²=23, x-2=±√(23/6), x=2±√(23/6)=2±1.95789, so x=3.95789 or 0.04211 approx. These are the zeroes.
