Answer:The total amount is 5x²-11x+14

Step-by-step explanation:
As per the given data in the question,
We have to calculate the total amount Sandhya has spent.
As per the question
It is given that,
Sandhya went to market to buy some fruits .she bought apple for rupees (2x+4),grapes for rupees (3x²-2x+1)and orange for rupees (9-11x+2x²)
That is ,
Amount for
Apple =(2x+4)
Grapes=(3x²-2x+1)
Orange=(9-11x+2x²)
Now to find total amount we have to add all these to find the total amount.
That is,
Total amount=(2x+4)+(3x²-2x+1)+(9-11x+2x²)
=3x²+2x²+2x-2x-11x+4+1+9
=5x²-11x+14
Now we can solve this equation using quadratic equation
That is,
X = -b(√b^2 -4ac)/ 2a
Solving this we get
X=11/10+(√159/10)i
X=11/10-(√159/10)i
One of the above will be the value of X
We can substitute this value of X into the equation 5x²-11x+14 to find the total amount she has spent.

Answer:

total cost comes out to be 5x²-11x+14.

Step-by-step explanation:

in the given question we have given the cost of different fruits like apples, grapes and oranges.

Sandhya has bought fruits like apples for 2x+4 and grapes for  (3x²-2x+1)

and orange for rupees  (9-11x+2x²)

we have to find the total amount she has spent

so cost of apple =       2x+4

   cost of grapes= 3x²-2x+1

cost of oranges = 2x²-11x+9

so when we add all the costs, we will be able to find out the total amount spent

total cost comes out to be 5x²-11x+14.

when we add some algebraic expressions it can be done by horizontal or columnar method

in horizontal method, we add them by segregating them according to their coefficients horizontally

and in columnar method, we list different coefficients of different variables and add them in columns.
