Question

factor the trinomials using the ac-method. s^2 - 6s + 3

Answer 1

for using ac-method we need to first know what are the values of a, b and c
a is the coefficient of the term with variable having power 2
b is the coefficient of the term with variable having power 1
c is the constant

In your question s^2 - 6s + 3
a = 1
b = -6
c = 3

so ac = 1*3 = 3
we have to find factors of 3 whose product is 3 but sum is -6
the only factors of 3 are 1 and 3 and they cannot add u to -6
so this question cannot be factorised using ac method

Answer 2

*cannot add up to -6
