Answer:
(3x + 4) • (3x - 4) hope we can be friends can i please get brainliest
Step-by-step explanation:
Step by step solution :
Step 1 :
Equation at the end of step 1 :
32x2 - 16
Step 2 :
Trying to factor as a Difference of Squares :
2.1 Factoring: 9x2-16
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 : 9 is the square of 3
Check : 16 is the square of 4
Check : x2 is the square of x1
Factorization is : (3x + 4) • (3x - 4)
