4.3 Factoring Trinomials when a = 1

A polynomial with 3 terms

• trinomial

• binomial

• monomial

When the 'c' term is negative but the 'b' term is positive, what type of terms should we have?  $x^2+bx\ -\ c$  

• Both Positive

• Both Negative

• Larger Term is Positive

• Smaller Term is Positive

When the 'c' term and 'b' are both negative, what type of terms should we have?  $x^2-bx\ -\ c$  

• Both Positive

• Both Negative

• Larger Term is Positive

• Smaller Term is Positive

When the 'c' term and 'b' are both positive, what type of terms should we have?  $x^2+bx\ +\ c$  

• Both Positive

• Both Negative

• Larger Term is Positive

• Smaller Term is Positive
