Simplify the polynomial equation (5x^2 - 7x +10) +(7x^2 - 11) +(-x^2 +7x- 2)<br>​
lorasvet [3.4K]

Answer:

11x^(2) - 3

Step-by-step explanation:

Remove the parentheses: (a)=a

=5x^2-7x+10+7x^2-11-x^2+7x-2

Group the like terms:

=5x^2+7x^2-x^2-7x+7x+10-11-2

Add the similar elements : 5x^2+7x^2-x^2=11x^2

=11x^2-7x+7x+10-11-2

Continue to add similar elements: -7x+7x=0

=11x^2+10-11-2

Then add or subtract the numbers:  10-11-2=-3

<u>FINAL ANSWER</u>:= <em>11x^(2)-3</em>

Answer:

TABLE

x      4        5      6       7       8        9         10        11         12

y    100    125   150    175    200    225   250      275     300

GRAPH

x    0      2       4        6         8            10       12

y    0     60    120     180     240       300      360

Value of y on graph - Value of y on table = 360 - 300 = 60
