Question

write the degree of a^3-3a^2b^2+5ab-c^2​

Answer 1

Answer:

2a2+5ab+2b2 [First multiply the coefficient of a^2 and coefficient of b^2 2

i.e. 2 x 2 = 4 Factorize 4 as if you multiply two numbers the product should be = 4

if you add the numbers it should be equal 5(the coefficient of a b term) 4 x 1 =4 , 4+1=5

2a2+4ab+1ab+2b2

2 a (a + 2 b) + b (a + 2 b)

(a + 2 b) ( 2 a + b)
