Question

How to multiply polynomials?

Answer 1

To multiply polynomials we have to make sure that the bases are same and then use this identity. a to the power m × a to the power n

Answer 2

Answer:

Multiplying polynomials:

Step 1:

→ First simplify the polynomial by cancelling the same terms if you can...

→ Multiply a single term with two or more terms..

Here are some easy formulas you can use to multiply polynomials:

→ (a+b)² = a²+2ab+b²

→ (a–b)² = a²–2ab+b²

→ a²–b² = (a+b)(a–b)

→ (x+a)(x–b) = x²+(a–b)(x)–ba

→ (x+a)(x–b) = x²+(a+b)(x)+ab

→ (x+y+z)² = x²+y²+z²+2xy+2yz+2xz

→ (x+y)³ = x³+y³+3xy²+3x²y

→ (x–y)³ = x³–y³+3xy²–3x²y

→ x³+y³+z³ = (x+y+z)(x²+y²+z²+2xy+2yz+2xz)+3xyz
