2y + 1
Obviously, both terms have the common factor "n". You get the other factor by dividing both terms by n. The result is "n + 2".
( x - y )2There isn't enough information to answer this question because they have two squared variables and you do not know what is being squared. You would first need to either know the value of one of the variables and an equation of the value of both of the variables before you would be able to factor.
All you can do to factor that expression is to divide both terms by y: y2 + 4y = y(y + 4)
Notice that we can factor out 2x from both terms on the LH side: ... 4x2+6x=0. The greatest common factor of 4 and 6 is 2 . The greatest common factor of x2 and x ...
Remember both 16 & 25 are squared numbers. 16 = 4^2 & 25 = 5^2 Hence we can write (4x)^2 - (5y)^2 Remember two squared terms with a NEGATIVE Between them will factor. ( 4x - 5y)(4x + 5y) Note the difference signs. NNB Two squared terms with a positive (+) between them DOES NOT factor.
A different factor. If you increase the distance by a factor of 10, the force decreases by a factor of 100, which is 10 squared. The same rule applies both to gravitational and to electrostatic forces.
Make it equal zero by subtracting 21x from both sides. 20x2 - 21x - 5 factors to (4x - 5)(5x + 1)
Yes. Both expressions are the same.
No, they do not.
x2 + 6x = 0 The only factor common to both terms is 'x'. x(x + 6) = 0 To solve this equation then one or both of the factors must equal zero. Then x = 0, or x + 6 = 0 which occurs when x = -6.
You cannot solve this statment as there is nothing to equate to it. However, it will factor. 9 - 4z^2 First we note that both '9' and '4' are squared numbers. 9 = 3^(2) & 4 = 2^(2) So we can re-write the statement as 3^(2) - (2z)^(2) Note that it now has two squared terms with a negative between them . This will factor to 3^(2) = (2z)^2 = ( 3 - 2z_)(3 + 2z) NOTE the different signs. NB Two squared terms with a positive(+) between them will NOT factor.
Yes, but not to the same question.
