Answer :
After solving the expression (x^2+3x-5)-(4x^2+3x-6) = -3x^2+1. So the option B is correct.
In the given question, we have to find which expression is equivalent to (x^2+3x-5)-(4x^2+3x-6).
The given options are:
A. 5x^2+6x-11
B. -3x^2+1
C. 3x^2+1
D. -3x^4+6x^2+1
To find which expression is equivalent to (x^2+3x-5)-(4x^2+3x-6). We firstly simplify the given expression.
To simplify the expression, we multiply the bracket of right hand side by minus sign. As we know that when we multiply the variable with minus sign the sign will change.
(x^2+3x-5)-(4x^2+3x-6) = x^2+3x-5-4x^2-3x+6
(x^2+3x-5)-(4x^2+3x-6) = -3x^2+1
After solving the expression (x^2+3x-5)-(4x^2+3x-6) = -3x^2+1. So the option B is correct.
