Question

what should be added to -4x^2+3x+1 to get 2x^2-9x+1​

Answer 1

Answer:

let the required number be A

so the equation will be

-4x²+3x+1+A = 2x²-9x+1

A= 2x²-9x+1-(-4x²+3x+1)

A= 2x²-9x+1+4x²-3x-1

A= 6x²-12x

so the required expression is 6x²-12x

hope it help

thankyou ;)

Answer 2

Answer:N=6x^2-12x

Explanation step-by-step

Let the N be added

Then,-4x^2+3x+1+N=2x^2-9x+1

# N=2x^2+4x^2-9x-3x+1-1

We will cut + and - so we will cut +1 and -1

So the answer is

# N=6x^2-12x
