Question

what must be subtracted from 2x2-3x+4 to get x2+2x-1

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Given:

Equation 1 : $2x^2-3x+4$

Equation 2 :$x^2+2x-1$

To Find:

What must be subtracted from$2x^2-3x+4$ to get $x^2+2x-1$

Solution:

Let y be the number that should be subtracted from $2x^2-3x+4$ to get $x^2+2x-1$

So, $2x^2-3x+4 -y=x^2+2x-1\\2x^2-x^2-3x-2x+4+1=y\\x^2-5x+5=y$

Hence$x^2-5x+5$ must be subtracted from $2x^2-3x+4$to get $x^2+2x-1$
