Question

a²-4b² factorisation​

Answer 1

Answer:

(a+2b)(a-2b)

Step-by-step explanation:

because when there is first sq ,Second Sq ten it will be one time minus one time plus

Answer 2

Answer:

Final result :

Final result : (a + 2b) • (a - 2b)

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

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

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 =

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 =

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

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 - B2Note : AB = BA is the commutative property of multiplication.Note : - AB + AB equals zero and is therefore eliminated from the expression.

Note : - AB + AB equals zero and is therefore eliminated from the expression.Check : 4 is the square of 2

Note : - AB + AB equals zero and is therefore eliminated from the expression.Check : 4 is the square of 2Check : a2 is the square of a1

Note : - AB + AB equals zero and is therefore eliminated from the expression.Check : 4 is the square of 2Check : a2 is the square of a1 Check : b2 is the square of b1

Note : - AB + AB equals zero and is therefore eliminated from the expression.Check : 4 is the square of 2Check : a2 is the square of a1 Check : b2 is the square of b1 Factorization is : (a + 2b) • (a - 2b)
