expand (2T-1)(pi+5)

Solution

expand

(2 T - 1) (π + 5)

Solution

2 π T + 10 T - π - 5

Solution steps

(2 T - 1) (π + 5)

= (π + 5) (2 T - 1)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = 2 T, b = - 1, c = π, d = 5

= 2 T π + 2 T \cdot 5 + (- 1) π + (- 1) \cdot 5

Apply minus-plus rules

+ (- a) = - a

= 2 π T + 2 \cdot 5 T - 1 π - 1 \cdot 5

Simplify

2 π T + 2 \cdot 5 T - 1 π - 1 \cdot 5 : 2 π T + 10 T - π - 5

= 2 π T + 10 T - π - 5
