Subtract (10x^2-13x++15x+1) and show the steps of how you got the answer

You use the quadratic formula.

x1 =

- (-28) - the square root of (-28) to the power of 2 minus 4 times 1 times 3 divided by 2 x 1 =

28 - 2 x the square root of 193 divided by 2 is 0.108.

x2 =

- (-28) plus the square root of (-28) to the power of 2 minus 4 times 1 times 3 divided by 2 times 1 =

28 plus 2 times the square root of 193 divided by 2 is 27.892

Extrema:

Min would equal (14, -193)

0.02040816326

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
