4(3x+2)-2 <br> find x show how you did it
olganol [36]

Answer:

Multiply 4 to the terms inside the parentheses.

(12x+8)-2

Remove the parentheses and equate it to zero.

12x+8-2 = 0

Simplify

12x+6 = 0

Transpose 6 to the other side.

12x = -6

Divide bith sides by 12.

12x/12 = -6/12

Simplify.

x = -6/12 or -½

Trying to factor as a Difference of Squares:

2.1 Factoring: 9x{}^{2}-1

Theory : A difference of two perfect squares, A{}^{2} - B{}^{2} can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A{}^{2} - AB + BA - B2 =

A{}^{2}- AB + AB - B2 =

A{}^{2} - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 9 is the square of 3

Check : 1 is the square of 1

Check : x{}^{2} is the square of x1

Factorization is : (3x + 1) • (3x - 1)

Final result :

(3x + 1) • (3x - 1)
