Answer:
Higher levels of organization are built from lower levels. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms.
Explanation:
x^2 - 2x + 6 = 0
Use the quadratic formula
x= <u>-b + or - squareroot b^2- 4 (a)(c)</u>
all over 2a
a = 1
b = -2
c = 6
x= <u>-(-2)+ or - squareroot (-2)^2 - 4(1)(6)</u> x= <u>2 + or - squareroot of -20</u>
all over 2 times 1 2
x= -20 <---- NO SOLUTION
