Answer 2

Answer:

(7z + 11) (11 - 7z)

Step-by-step explanation:

STEP1:

Equation at the end of step 1

Equation at the end of step 1 121 - 72z2

STEP2:

Trying to factor as a Difference of Squares:

Factoring: 121-49z2

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) (A-B)

Proof : (A+B) (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

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

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

Check : 121 is the square of 11

Check : 49 is the square of 7

Check : z2 is the square of z1

Factorization is :(11 + 7z) (11 - 7z)

HOPE IT HELPFUL FOR YOU.
