Question

20
( a2 + 4 - 4a) ÷ (a -2) = ?​

Answer 1

Answer:

The first term is, a2 its coefficient is 1 .

The middle term is, -4a its coefficient is -4 .

The last term, "the constant", is -20

Step-1 : Multiply the coefficient of the first term by the constant 1 • -20 = -20

Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is -4 .

-20 + 1 = -19

-10 + 2 = -8

-5 + 4 = -1

-4 + 5 = 1

-2 + 10 = 8

-1 + 20 = 19

Observation : No two such factors can be found !!
