U see here 5 is common
OpenStudy (theviper):
\[5(x^2+4x+3)\]
OpenStudy (anonymous):
yeaaa its common
OpenStudy (anonymous):
A.
x - 5
B.
x + 1
C.
x - 1
D.
x + 5

noooo idk how to do this
OpenStudy (theviper):
K! first find the value of x in option A, i.e., x=5
OpenStudy (theviper):
Than put this value of x in the eq.
OpenStudy (theviper):
After putting solve the eq. if the ans is zero than A is a factor of the given trinomial or ans is not zero than it is not.
OpenStudy (theviper):
Similarly, check in every option.

To, find the zeroes of a trinomial u can study a ninth class book
OpenStudy (anonymous):
5(x+1)(x+3)
ans. is B
OpenStudy (anonymous):
Seriously now, any expression of form
ax^n + (a1)x^(n-1) + .... + (an-1)x + an
is a polynomial,!
A trinomial has three different variables For eg. x^3 + xyz + y^2 + 2z^2 + z^3
and binomial has 2 different variables, like x+y or X^2 + y^2 + xy
