Question

All the formal of polynomial??​

Answer 1

Answer:

Polynomial Identities

• (x + y)2= x2 + 2xy + y2

• (x – y)2= x2 – 2xy + y2

• x2– y2 = (x + y)(x – y)

• (x + a)(x + b) = x2+ (a + b)x + ab.

• (x + y + z)2= x2 + y2 + c2 + 2xy + 2yz + 2zx.

• (x + y)3= x3 + y3 + 3xy (x + y)

• (x – y)3= x3 – y3 – 3xy (x – y)

• x3+ y3 = (x + y)(x2 – xy + y2)

Answer 2

Answer:

Polynomial equation is of four types :

Monomial: This type of polynomial contains only one term. For example, x2 , x, y, 3y, 4z

Binomial: This type of polynomial contains two terms. For example, x2 – 10x

Trinomial: This type of polynomial contains three terms. For example, x2 – 10x+9

Quadratic Polynomial: This type of polynomial contains four terms. For example, x3+2x2 – 10x+7
