Answer:

a - b2

Step-by-step explanation:

STEP 1 :

Trying to factor as a Difference of Squares:

1.1 Factoring: a-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

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

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

Check : a1 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares

Final result :

a - b2

HOPE THIS HELPS!

1) Find the missing side.

kari74 [83]

Answer:

25inch

Step-by-step explanation:

Ok so there is something called a Pythagorean theorem.

It's a²+b²=c²

It works on right triangles

C is the longest side or the side not touching the right angle

and a and b is the other 2 sides

so the missing side is 24²+7²=Missing side or c²

24²=576 and 7²= 49

576+49=625

$\sqrt{625}$ =25

What is the completely factored form of 8x2 - 50?

bogdanovich [222]

Answer:

2(2x-5)(2x+5)

Step-by-step explanation:

I think you meant to say 8x^2-50. If so then factoring this down should be easy. Since there is no x value in the middle the equation will have a positive and a negative number. This is also a perfect square therefore, this factors down to: 2(2x-5)(2x+5).
