Subtract these polynomials (x^2+5x+2)- (5x^2-x-2)

Step-by-step explanation:

Here,

the given polynomials are;

(x^2+5x+2)-(5x^2-x-2)

now, when we open bracket of second polynomial we get,

=x^2+5x+2-5x^2+x+2

combining like terms and simplifying them we get;

=x^2-5x^2+5x+x+2+2

=-3x^2+6x+4.

Therefore, the answer is-3x^2+6x+4 or, taking - (minus) commo it will be -(3x2-6x-4).

Hope it helps

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
