Question 96688: Can you please help with the following problem? 4m%5E2-4m%2B2 m= 1%2F4
I first start with factoring out the exponent and I get: 4%2F1 * 1%2F4 * 1%2F4 - 4%2F1 * 1%2F4 + 2%2F1. Then I lose it. I know the answer is 5%2F4 but I can't get it. I keep getting 2. Please help. Thank you.

4m%5E2-4m%2B2 Start with the given expression


4%281%2F4%29%5E2-4%281%2F4%29%2B2 Plug in m=1%2F4


4%281%2F16%29-4%281%2F4%29%2B2 Square 1%2F4 to get 1%2F16


4%2F16-4%2F4%2B2 Multiply 4%2A%281%2F16%29 to get 4%2F16. Multiply 4%2A%281%2F4%29 to get 4%2F4



1%2F4-1%2B2 Reduce the fractions


1%2F4%2B1 Add -1 and 2 to get 1


1%2F4%2B4%2F4 Rewrite 1 as 4%2F4


5%2F4 Combine the fractions
