When the factor of a trinomial are (X+P) and (x+q) then coefficient of the x-term in the trinomial is A The sum of p and q B the
difference of P and Q C the product of p and q D the quotient.
2 answers:
The answer should be A, the sum of p and q.
Plug in a value for p and q to figure this out.
Here, I'm using 4 for p and 5 for q.
(x+4)(x+5)
x^2+5x+4x+20
x^2+9x+20
Here, the coefficient for the x term is 9 and 9 is the sum of p and q (4+5).
( x + p)(x + q)
= x^2 + qx + px + pq
= x^2 + (p + q)x + pq
ITs A The sum of p and q
