expand (s-3)(s+2=5)

Solution

expand

(s - 3) (s + 2 = 5)

Solution

s^{2} + 2 s = 5

Solution steps

(s - 3) (s + 2 = 5)

= (s - 3) (s + 2 \cdot 5 =)

Apply FOIL method:

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

a = s, b = - 3, c = s, d = 2 = 5

ss + s \cdot 2 = 5 + (- 3) s + (- 3) \cdot 2 = 5

Apply minus-plus rules

+ (- a) = - a

ss + 2 s = 5 - 3 s - 3 \cdot 2 = 5

Expand

ss + 2 s : s^{2} + 2 s

s^{2} + 2 s = 5
