Answers
4x^2-6x + 22
______________
x^2 + 2x-3 Il 4x^4 + 2x^3-2x^2+x-1
4x^4 + 8x^3-12x^2
__________________________
-6x^3 + 10x^2 + x-1
-6x^3-12x^2 + 18x
___________________________
22x^2-17x-1
22x^2 + 44x-66
___________________________
-373x + 65
The amount of money she need to have
(x^2+2x-3)(4x^2-6x+22)
4x^4+2x^3-2x^2+62x-66
Let's do it
Amount given by mother
p(x)=4x^4+2x^3-2x^2+x-1
Cost of one box g(x) =x^2+2x-3
Number of boxes
=quotient of {p(x)/g(x)}
Remainder=Amount donated
THE DIVISION is in the attachment.
Number of boxes
=4x^2-6x+22
Amount donated= -61x+65
Amount that rehman must
have to buy exact number of boxes
=p(x)- remainder
=(4x^4+2x^3-2x^2+x-1)-(-61x+65)
=4x^4+2x^3-2x^2+62x-66
Thanks for asking the question and your time.
