Question

what must be added to 5x^3-2x^2+6X+7 to make the sum x^3+3x^2-X+1 ?​

Answer 1

Step-by-step explanation:

sum x^3+3x^2-X+1

one addend= 5x^3-2x^2+6X+7

adden+addend=sum

other addend= sum -addend

= x^3+3x^2-X+1-(5x^3-2x^2+6X+7)

= x^3+3x^2-X+1-5x^3+2x^2-6X-7

= x^3-5x^3+3x^2+2x^2-x-6X+1-7

= -4x^3+5x^2-7x-6

so we must add -4x^3+5x^2-7x-6 to 5x^3-2x^2+6X+7 to make the sum x^3+3x^2-X+1 ?
