Tuff I don’t understand it but for question four the answer is
9 LCM=3x3=9, 45 LCM=5x9=45, 81 LCM=9x9=81
26/ 15 but make it into a mixed number you can do it!
2x^2+2x-40=0
2x^2+10x-8x-40=0
2x(x+5)-8(x+5)=0
(2x-8)(x+5)=0
2(x-4)(x+5)=0
x=-5 and 4
If you graph it, the zeros are just the values of x when the curve meets the x axis...
