Question

Factorise: (a-b)2+(a-b)​

Answer 1

Answer:

Note that you don't even need to factor it, just expand the expression.

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2=(a2+b2+2ab)−(a2+b2−2ab)

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2=(a2+b2+2ab)−(a2+b2−2ab)=a2+b2+2ab−a2−b2+2ab

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2=(a2+b2+2ab)−(a2+b2−2ab)=a2+b2+2ab−a2−b2+2ab=4ab

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2=(a2+b2+2ab)−(a2+b2−2ab)=a2+b2+2ab−a2−b2+2ab=4abIf you have to factor it, remember the difference of squares a2−b2=(a+b)(a−b). In this case, a2 is (a+b)2, and b2 is (a−b)2.

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2=(a2+b2+2ab)−(a2+b2−2ab)=a2+b2+2ab−a2−b2+2ab=4abIf you have to factor it, remember the difference of squares a2−b2=(a+b)(a−b). In this case, a2 is (a+b)2, and b2 is (a−b)2.(a+b)2−(a−b)2

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2=(a2+b2+2ab)−(a2+b2−2ab)=a2+b2+2ab−a2−b2+2ab=4abIf you have to factor it, remember the difference of squares a2−b2=(a+b)(a−b). In this case, a2 is (a+b)2, and b2 is (a−b)2.(a+b)2−(a−b)2=(a+b+a−b)(a+b−(a−b))

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2=(a2+b2+2ab)−(a2+b2−2ab)=a2+b2+2ab−a2−b2+2ab=4abIf you have to factor it, remember the difference of squares a2−b2=(a+b)(a−b). In this case, a2 is (a+b)2, and b2 is (a−b)2.(a+b)2−(a−b)2=(a+b+a−b)(a+b−(a−b))=(2a)(a+b−a+b)

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2=(a2+b2+2ab)−(a2+b2−2ab)=a2+b2+2ab−a2−b2+2ab=4abIf you have to factor it, remember the difference of squares a2−b2=(a+b)(a−b). In this case, a2 is (a+b)2, and b2 is (a−b)2.(a+b)2−(a−b)2=(a+b+a−b)(a+b−(a−b))=(2a)(a+b−a+b)=(2a)(2b)

Note that you don't even need to factor it, just expand the expression.(a+b)2−(a−b)2=(a2+b2+2ab)−(a2+b2−2ab)=a2+b2+2ab−a2−b2+2ab=4abIf you have to factor it, remember the difference of squares a2−b2=(a+b)(a−b). In this case, a2 is (a+b)2, and b2 is (a−b)2.(a+b)2−(a−b)2=(a+b+a−b)(a+b−(a−b))=(2a)(a+b−a+b)=(2a)(2b)=4ab

Answer 2

Answer:

$(a-b)(a-b + 1)$

Step-by-step explanation:

$(a-b)^{2} + (a-b)\\= (a-b)(a-b) + (a-b)\\= (a-b)(a-b+1)$
