Question

Subtract 5y^2-6y-115y

Answer 1

Given:

We need to subtract the polynomial $5y^2-6y-11$ from $6y^2+2y+5$

We need to subtract the two polynomials and write the answer in standard  form.

Subtraction:

Let us subtract the polynomial $5y^2-6y-11$ from $6y^2+2y+5$

Thus, we have;

$6y^2+2y+5-(5y^2-6y-11)$

Removing the parenthesis, we get;

$6y^2+2y+5-5y^2+6y+11$

Adding the like terms, we have;

$y^2+8y+16$

Thus, the value of the two polynomials after subtraction is $y^2+8y+16$

Therefore, the polynomial in standard form after subtraction is $y^2+8y+16$
