expand (x-1)(x+5=3)

Solution

expand

(x - 1) (x + 5 = 3)

Solution

x^{2} + 5 x = 3

Solution steps

(x - 1) (x + 5 = 3)

= (x - 1) (x + 5 \cdot 3 =)

Apply FOIL method:

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

a = x, b = - 1, c = x, d = 5 = 3

xx + x \cdot 5 = 3 + (- 1) x + (- 1) \cdot 5 = 3

Apply minus-plus rules

+ (- a) = - a

xx + 5 x = 3 - 1 \cdot x - 1 \cdot 5 = 3

Expand

xx + 5 x : x^{2} + 5 x

x^{2} + 5 x = 3
