Determine which of the lines, if any, are parallel. Explain. line a passes through (-1,-2) and (1,0)
line b passes through (4,2) and (2,-2)
line c passes through (0,2) and (-1,1)

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

∠cbe and ∠deb are same-side interior angles.

i took the test

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

is there supposed to be a diagram or a graph for this one? ?
