Question

factorisation of quadratic polynomials (any one )​

Answer 1

The clue lies in the solutions of the equation x2 − 2x − 15 = 0 (called a quadratic equation). If we factorise the quadratic, the equation can be written as (x − 5)(x + 3) = 0. But a product of two factors can only be equal to zero if one or the other factor is equal to zero.

Answer 2

Answer:

x²-4x+3

x²-(3+1)x+3

x²-3x-x+3

x(x-3)-1(x-3)

(x-3) (x-1)
