Question

Write all the formulas of polynomial and give all the example's of each .​

Answer 1

Answer:

• (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)
