amistre64 · Answer

just try to remember how trinomial are formed; and usually it means you are dealing with a quadratic

amistre64 · Answer

(x+b) (x+c)

      x+b
      x+c
--------
x^2 +bx
       +cx      +bc
----------------
x^2 +(b+c)x +(bc)

amistre64 · Answer

to factor is to undo what you multiplied together

amistre64 · Answer

x^2 +3x -10 for example;  we need to find 2 numbers such that:

(bc) = -10  and:

(b+c) = 3

amistre64 · Answer

(x+b) (x+c)  is the factored form then:

1,10; -1(10) = -10, but -10 +1 not= 3 ; those aint workin'

-2,5; -2(5) = -10;   5 -2 = 3; thatll work

(x+5)(x-2)
