1) (2t + - 1) (t + 5) becomes (2t - 1) (t + 5) = **2t² + 9t - 5**

Steps in multiplying binomials:

a) Multiply the **FI**RST TERMS ⇒ (2t)(t) = **2t² **

b) Multiply the **O**UTER TERMS** **⇒ (2t) (5) = **10t**

c) Multiply the **I**NNER TERMS ⇒ (-1) (t) = -**1t**

d) Multiply the **L**AST TERMS ⇒ (-1)(5) = -**5**

Combine the like terms, if any:

2t² + 10t - 1t - 5 = **2t² + 9t - 5**

2) (x + 4) (x + 4) = x² + 4x + 4x + 16

** = x² + 8x + 16 ** (Perfect Square Trinomial)

3) (2r -5) (2r - 5) = 4r² - 10r - 10r + 25

** = 4r² -10r + 25 (**Perfect Square Trinomial)

4) (3 - 4m)2 = **6 - 8m or -8m + 6**

Please do the rest as practice exercises.
