Question

4r squared minus 4r plus 1

Answer 1

simplify the exponents so what is 4x4? then subtract 4r

Answer 2

Is that 4r^2 or (4r)^2?

Answer 3

4r^2 - 4r + 1 = 0

(2r - 1)(2r - 1) = 0 (since it is factorable)

r = -.5 and r = -.5

Answer 4

Therefore, one root.

Answer 5

then you can't have a number and number with a variable can't combine so you have s simplified expression
