Question

What must be added to 5 x cube minus 2 x square + 6 X + 7 to make the sum x cube + 3 x square minus x + 1

Answer 1

Answer:

-4x³+5x²-7x-6

Step-by-step explanation:

The given equation must be:

g(x)=5x³-2x²+6x+7

We are supposed make it as,

f(x)=x³+3x²-x+1

Hence our equation is,

g(x)+y=f(x)

y=f(x)-g(x)

y=(x³+3x²-x+1)-(5x³-2x²+6x+7)

y=x³(1-5)+x²(3+2)+x(-1+6)+(1-7)

y=-4x³+5x²-7x-6
