Question

(x - 4)(x + 2) = 0 ​

Answer 1

Answer:

Given:-

⇢ $\sf{(x - 4) (x + 2) = 0}$

ㅤ

Find:-

⇢ Factories the given expression.

ㅤ

Calculations:-

⇢ $\sf{(x - 4) (x + 2) = 0}$

ㅤ

Simplify both the sides:

⇢ $\sf{x^{2} - 2x - 8 = 0}$

ㅤ

Factor left hand side of the equation:

⇢ $\sf{(x + 2) (x - 4) = 0}$

ㅤ

Now, add factors equal to zero:

⇢ $\sf{x + 2 = 0}$

or $\sf{x - 4 = 0}$

ㅤ

⇢ $\sf{x = -2}$

or $\sf{x = 4}$

ㅤ

Therefore, this is the required answer.
