expand (x+1)(x+8=0)

Solution

expand

(x + 1) (x + 8 = 0)

Solution

x^{2} + 8 x = 0

Solution steps

(x + 1) (x + 8 = 0)

= (x + 1) (x + 8 \cdot 0 =)

Apply FOIL method:

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

a = x, b = 1, c = x, d = 8 = 0

xx + x \cdot 8 = 0 + 1 \cdot x + 1 \cdot 8 = 0

xx + 8 x = 0 + 1 \cdot x + 1 \cdot 8 = 0

Expand

xx + 8 x : x^{2} + 8 x

x^{2} + 8 x = 0
