3/4a2+3b2)4(a2-2/3b2)
Final result :
(a2 + 4b2) • (3a2 - 2b2)
Step by step solution :
Step 1 :
2 Simplify — 3
Equation at the end of step 1 :
3 2 (((—•(a2))+(3•(b2)))•4)•((a2)-(—•b2)) 4 3
Step 2 :
Equation at the end of step 2 :
3 2b2 (((—•(a2))+(3•(b2)))•4)•((a2)-———) 4 3
Step 3 :
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 3 as the denominator :
a2 a2 • 3 a2 = —— = —————— 1 3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
a2 • 3 - (2b2) 3a2 - 2b2 —————————————— = ————————— 3 3
Equation at the end of step 3 :
3 (3a2-2b2) (((—•(a2))+(3•(b2)))•4)•————————— 4 3
Step 4 :
Equation at the end of step 4 :
3 (3a2-2b2) (((—•(a2))+3b2)•4)•————————— 4 3
Step 5 :
3 Simplify — 4
Equation at the end of step 5 :
3 (3a2 - 2b2) (((— • a2) + 3b2) • 4) • ——————————— 4 3
Step 6 :
Equation at the end of step 6 :
3a2 (3a2 - 2b2) ((——— + 3b2) • 4) • ——————————— 4 3
Step 7 :
Rewriting the whole as an Equivalent Fraction :
7.1 Adding a whole to a fraction
Rewrite the whole as a fraction using 4 as the denominator :
3b2 3b2 • 4 3b2 = ——— = ——————— 1 4
Adding fractions that have a common denominator :
7.2 Adding up the two equivalent fractions
3a2 + 3b2 • 4 3a2 + 12b2 ————————————— = —————————— 4 4
Equation at the end of step 7 :
(3a2 + 12b2) (3a2 - 2b2) (———————————— • 4) • ——————————— 4 3
Step 8 :
Step 9 :
Pulling out like terms :
9.1 Pull out like factors :
3a2 + 12b2 = 3 • (a2 + 4b2)
Equation at the end of step 9 :
(3a2 - 2b2) 3 • (a2 + 4b2) • ——————————— 3
Step 10 :
Trying to factor as a Difference of Squares :
10.1 Factoring: 3a2-2b2
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 : 3 is not a square !!
Ruling : Binomial can not be factored as the
difference of two perfect squares
Final result :
(a2 + 4b2) • (3a2 - 2b2)
