Question

Which expression is equivalent to (x+1)^2-g/x+4?

Answer 1

Answer:

$\frac{x^2+2x+1-g}{x+4}$

Step-by-step explanation:

We are given the following expression and we are to evaluate it and find the expression equivalent to it:

$\frac { ( x + 1 ) ^ 2 - g } { x + 4 }$

We know that $(a+b)^2=a^2+2ab+b^2$ so we will expand the term $( x + 1 ) ^ 2$ according to this to get:

$(x+1)^2=x^2+2x+1$

Therefore, we get the expression:

$\frac { x ^ 2 + 2 x + 1 - g } { x + 4 }$
