Pulling out like terms
4.1 Pull out like factors :
48x2 - 75y2 = 3 • (16x2 - 25y2)
Trying to factor as a Difference of Squares:
4.2 Factoring: 16x2 - 25y2
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 : 16 is the square of 4
Check : 25 is the square of 5
Check : x2 is the square of x1
Check : y2 is the square of y1
Factorization is : (4x + 5y) • (4x - 5y)
Final result :
3 • (4x + 5y) • (4x - 5y)
Answer:
3(4x-5 y) (4 x + 5 y)
