Step Type Explanation Answer

1

Problem

Solve the equation:
\$ x^2 - 2x -24 = 0 \$

2

Step

By using the factorisation method

\$ x^2 - 6x + 4x -24 = 0 \$

3

Step

After simplication we get

\$ x(x-6) + 4(x-6) = 0 \$

4

Step

Taking (x-6) has common

\$ (x - 6)(x + 4) = 0 \$

5

Step

We know that if ab = 0 then a=0,b=0

x - 6 = 0, x + 4 = 0

6

Step

Moving constant terms to the left side

x = 6 , x = -4
