First of all, some terminology: it is not an equation; there is no equal sign. It is a mathematical expression. You can’t “solve” it, but you can “expand” it: multiply each term in the second part by each term in the first part:(3x-4y)(2a+3b)
How can you simplify this equation if there are no common terms?
How would you complete this equation step by step?
Islandchild said:Any chance the expressions below are just as easy to factor?
1) 125x^3 - 8y^3
This one is easy, if you recognize that it's a difference of cubes.
(Both 125 and 8 are cubes.)
There are special factoring formulas for both a sum of cubes and a difference of cubes.
2) 2(5x-1)^3 - (5x-1)^2
Hint: Factor out a factor of (5x - 1)^2 from each term, then simplify.
In other words, fill in the blanks below and then simplify what's inside the square brackets.
(5x - 1)^2 * [ ____ - ____ ]
Do you mean "the sum of the factors of which equals the respective number"?Rodsh said:Looking for two perfect numbers, the factors of which equals the respective number
