expand (x-2)(x+5=0)

Solution

expand

(x - 2) (x + 5 = 0)

Solution

x^{2} + 5 x = 0

Solution steps

(x - 2) (x + 5 = 0)

= (x - 2) (x + 5 \cdot 0 =)

Apply FOIL method:

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

a = x, b = - 2, c = x, d = 5 = 0

xx + x \cdot 5 = 0 + (- 2) x + (- 2) \cdot 5 = 0

Apply minus-plus rules

+ (- a) = - a

xx + 5 x = 0 - 2 x - 2 \cdot 5 = 0

Expand

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

x^{2} + 5 x = 0
