Question

X2 - 6x + 9
help solve

Answer 1

The answer is 3... If you used quadratic formula you will get it... that’s plus or minus root b^2-4ac all over 2a where a=1 b=-6 and C=9... l hope it helped??

Answer 2

3

lazy approach was with a graphic plotting program, but you can also calculate it. with the pq-formula.

p = -6

q = 9

x = -p/2 +- sqrt( (p/2)² - q)

x = -(-6)/2 +- sqrt ( (-6/2)² - 9)

x = 3 +- sqrt(9-9)

x = 3 +- sqrt(0)

x = 3 +- 0

x = 3
