answer
The standard algebraic identities are:
(x + a)(x + b) = x2 + (a + b) x + ab. (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca. (a + b)3 = a3 + b3 + 3ab (a + b) ... a3 + b3 + c3– 3abc = (a + b + c)(a2 + b2 + c2 – ab – bc – ca
Step-by-step explanation:
Identity I (a+b)2 = a2+2ab+b2
Identity II (a-b)2 = a2- 2ab+b2
Identity III a2-b2= (a+b) (a-b)
Identity IV (x+a) (x+b) = x2+(a+b) x+ab

Answer:
- monomials =3x,4
- binomials = 2b+3,5p-7q
- trinomial=2a-3b+5b
- polynomial ( an algebraic expression of two or more than two terms) = 3x-7,3x-x+4y, 5b-2b+ 8a-7c
