Question

find the value of polynomial P(x)= x²+2x+1 at x=1and x=2​

Answer 1

$\huge\mathfrak\blue{answer}$

polynomial p(x) = x² + 2x + 1

• When x = 1
• (1)² + 2(1) + 1
• 1 + 2 + 1
• 4

• When x= 2
• (2)² + 2(2) + 1
• 4 + 4 + 1
• 9

___The value of polynomial p(x) = x² + 2x + 1 when x = 1 is 4 and when x = 2 is 9__

Answer 2

Question:-

Find the value of polynomial P(x)= x²+2x+1 at x=1and x=2.

$\huge\mathcal\blue{Answer}$

• Polynomial = x²+2x+1
• There are two case given let us solve it.

_________________

Case 1:-

❑ When x is 1.

✔ x²+2x+1

✔ (1)² + 2x1 + 1

✔ 1 + 2 + 1

✔ 4

• So when x is 1 the value is 4.

---------------------------

Case 2:-

❑ When x is 2.

✔ x²+2x+1

✔ (2)² + 2(2) + 1

✔ 4 + 4 + 1

✔ 9

• So when x is 2 the value is 9.

More information:-

➦ There are some degrees of polynomial like 1, 2, 3 are called linear , quadratic and cubic polynomial.

➦ The real number where it is value of that equation is called as zero of polynomial. Ex:- Here in this equation 1,2 are zeroes.
