Question

If p( y)= 2y³ - 6y² -5y + 7 then find p(2) & p (0)

please fast and correct and I will mark you as a brainlist​

Answer 1

Answer:

$\huge{}{} \pink{answer}{ \:}$

• Since p(2) = 2×2^3-6×2^2+7

------> 16-24+7

16+7-24 = -1

Since p(0) = 2×0^3-6×0^2+7

----> 0+0+7

p(0) = 7 and p(2) = -1

Answer 2

Answer:

• p(2) = -11

• p(0) = 7

Step-by-step explanation:

• Finding value of p at 2.

$\implies \: p(2) = 2 {(2)}^{3} - 6 {(2)}^{2} - 5(2) + 7$

$\implies \: p(2) = 2(8) - 6(4) - 10 + 7$

$\implies \: p(2) = 16 - 24 - 10 + 7$

$\implies \: p(2) = - 11$

• Finding the value of p at 0.

$\implies \: p(0) = 2 {(0)}^{3} - 6(0) - 5(0) + 7$

$\implies \: p(0) = 2(0) - 6(0) - 5(0) + 7$

$\implies \: \: p(0) = 0 - 0 - 0 + 7$

$\implies \: p(0) = 7$

Polynomials :-

• polynomials : Polynomial are variable based dialect in the language of maths.

• In a common language , polynomials are defined as a string of variables and numbers put together.

• Highest power of a polynomial is called degree of polynomial.

• A constant polynomial is nothing but a monomial with degree zero.

• Equation: A condition or a constraint placed on x and y coordinates.

• Curve: A union of points that satisfy a particular condition.

• Remainder theorem: When p(x) is divided by (x - a) then the remainder is given by p(a).
