expand (x-3)(x=+2)

Solution

expand

(x - 3) (x = + 2)

Solution

x^{2} = - 6

Solution steps

(x - 3) (x = + 2)

= (x - 3) (= x + 2)

Apply FOIL method:

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

a = x, b = - 3, c = x =, d = 2

xx = x \cdot 2 + (- 3) x = (- 3) \cdot 2

Apply minus-plus rules

+ (- a) = - a

xx = 2 x - 3 x = - 3 \cdot 2

Simplify

xx = 2 x - 3 x = - 3 \cdot 2 : x^{2} = - 6

x^{2} = - 6
