Using the method of splitting of the middle term explaining the process of factoring x + (a + b)x + ab. NEED HELP !!

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

(-5,-28)

i graphed to on desmos.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
