Evaluate expression when a=6 a2-6a+4

Hi again :)

a = 6

a² - 6a + 4

All you have to do is to replace 6 where you see the a

(6)²  - 6(6) + 4

36 - 36 + 4

= 4

Yep, that easy!

I hope this helps! Let me know if you have any questions :)

The first step to solving this problem is to plug in 6 where you see a in the expression
-6² - 6 (-6) + 4
the first step to solving this is to evaluate the power
-36 - 6x (-6) + 4
next you will multiply the numbers
-36 + 36 + 4
finally,, eliminate the opposite of the expression to find your answer
4
this means that the correct answer to your question is 4.
let me know if you have any further questions
