(3x + 2) Adding fractions that have a common denominator: 4.2 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.

Rewriting the whole as an Equivalent Fraction :

3.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 3 as the denominator : Grease free online.

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

Step 4 :

Pulling out like terms :

Day one alternative. 4.1 Pull out like factors :
9x² + 6x = 3x • (3x + 2)

Adding fractions that have a common denominator :

Adding fractions that have a common denominator :

6.2 Adding up the two equivalent fractions

Trying to factor by splitting the middle term

Soulver 2 6 9 X 2

6.3 Factoring 27x² + 19x - 3
The first term is, 27x² its coefficient is 27.
The middle term is, +19x its coefficient is 19.
The last term, 'the constant', is -3
Step-1 : Multiply the coefficient of the first term by the constant 27 • -3 = -81
Step-2 : Find two factors of -81 whose sum equals the coefficient of the middle term, which is 19.

Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Soulver 2 6 9 X 2 54
