3) A polynomial of degree two is called a ______polynomial.
4) The coefficient of x in the polynomial, 6x³ -x is _______.
5) The p(1) of the polynomial x² - 2x =______.​

Answer 1

Answer:

$\huge\green{\mid{\fbox{\tt{ANSWER❤-❁☆}}\mid}}$

1).) x³- x² + 4x + 7 is a polynomial in _________.

➡REAL AND COMPLEX ZEROES.

2).The degree of the polynomial t²+4 is_______.

➡QUADRATIC POLYNOMIAL.

3).A polynomial of degree two is called a ______polynomial.

➡QUADRATIC POLYNOMIAL.

4).The coefficient of x in the polynomial, 6x³ -x is _______.

➡ -6³ is the degree of polynomial.

5).The p(1) of the polynomial x² - 2x =______.

➡Given polynomial equation x2+x-p (p+1)

x2+x-p(p+1)=0

On factorising we get,

x2+(p+1)x-px-p(p+1)=0

x(x+p+1) -p(x+p+1)=0

(x+p+1)(x-p)=0

x=-p-1, and x= p

The zeros of polynomial are: p-1 and p
