so you can not make the number smaller or reduce the fraction
ex.u can not simplify 11 over 12 because 11 is a prime number
Answer:
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "b2" was replaced by "b^2". 1 more similar replacement(s).
STEP
1
:
5a + 5b
Simplify ———————
a2 - b2
STEP
2
:
Pulling out like terms
2.1 Pull out like factors :
5a + 5b = 5 • (a + b)
Trying to factor as a Difference of Squares:
2.2 Factoring: 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 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (a + b) • (a - b)
Canceling Out :
2.3 Cancel out (a + b) which appears on both sides of the fraction line.
Final result :
5 / a -b
Step-by-step explanation:
If I'm not mistaken, this is cross multiplying.
The first one is 2/2 = 6/10
You will multiply 2x10= 20
Multiply 6x X= 6x
You will divide 6 into 20.
20 / 6 = 3.33333
Second:
8/x =4/11
Multiply 8 x 11= 88
Multiply 4 x X = 4x
Divide 88/4
88/4=22
Answer:
(x,y)= (-6/5, -3)
