Question

When x =7, x²-2x+6=​

Answer 1

41

Explanation:

step 1. first, you should plug in all the x's. x² is 49, 2x is 14. The

equation would then be 49-14+6 which is 41

2x would be 2 x 7 because when 2 numbers are touching, they are to be multiplied.

x² would be 7 x 7 because, when you have a number to the power of 2, you multiply it by itself.

and finally you would get, 49-14+6 and according to PEMDAS, the eqaution hsould go left to right leaving us with the answer of 41.

i hope you understand this. :)
