<em>when we solve the equation it will become
x</em>² + 9x<em>= 0
now here a = 1 , b = 9 and c = 0
by using quaderatic formula
x = -b +,-</em>√<em>b </em>²<em>- 4ac / 2a ( 2a is divided by all terms )
by putting values
x = - 9 +,</em><em>- </em>√<em>81 / 2(1) ( </em>√<em>81 = 9)</em><em>
x = -9 + 9 / 2 and x = -9 -9 /2
x = 0 and x = -18 /2 = -9
now there are two values for x one is- 9 and other is 0
so we put -9 as the value of x then answer will be zero..</em>
Answer:
a. Point.
b. Vertex.
c. Line.
d. Line segment.
e. Ray.
Step-by-step explanation:
a. <u>Point</u>: a location, has no dimension. Also, a point doesn't have a size i.e no length, depth, breadth or height.
b. <u>Vertex</u>: is the common endpoint of two segments or rays that form the "corner" of an angle.
c. <u>Line</u>: is an infinite number of points extending in opposite directions that has only one dimension.
d. <u>Line segment</u>: is part of a line that has two endpoints.
e. <u>Ray</u>: is part of a line that has one endpoint and continues in one direction infinitely.
