Answer:
x = 9 ± √14
Step-by-step explanation:
x² − 18x + 67 = 0
Move the constant to the other side:
x² − 18x = -67
Take half of -18, square it, and add to both sides.
(-18/2)² = (-9)² = 81
x² − 18x + 81 = -67 + 81
x² − 18x + 81 = 14
Factor the perfect square:
(x − 9)² = 14
Solve for x:
x − 9 = ±√14
x = 9 ± √14
2y+14=28
-14=-14

Mmmmmmmmmmmmmoooooooooooooooooooooooooooooooooooooooooooooooooosssssssssssssssssssssssssssseeeeeeeeeeeeeeeeeeeeeeeee
Lineare means it is in a straight line aka highest exponent on any placeholder is 1
y=2^2-4
y^1=2^2-4
yep
answer is this is linear
