Perform the indicated operation to write given polynomial in standard form: (x^2+ 7x − 12)(x^2 − 9x +1)

The expression in standard form will be      

Step-by-step explanation:

We have given polynomial

We have to write the given polynomial in standard form

For writing in standard form we have to first multiply then write in order

So after multiplication

So the expression in standard form will be

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
