Answer:
Step-by-step explanation:
The given quadratic equation is
Subtract 7 from both sides.
...(1)
If an expression is , then we add to make it perfect square.
Add 9 on both sides in equation (1).
Taking square root on both sides.
Add 3 on both sides.
Therefore, the correct order is F, A, D, C, E and B.
option f
option a
option d
option c
option e
option b
we have x^2 - 6x + 7 = 0
f) x^2 - 6x = -7
a) x^2 - 6x + 9 = -7+9
d) (x-3)^2=2
c)
e) x-3=+-
b) x=3+-
sure
she multiplied it 3 times, so, i dont think 8 should be negative.
It isn't necessary but having a positive coefficient for makes things like completing the square and factoring easier.
