Factor. 9x2−30xy+25y2

The factor form is:

Step-by-step explanation:

When the factor of the expression is required to be found, then take the common terms, or can be done by using the standard formulas, for example,

Now, here we have to find the factor of the expression:

So now, we can see that this is the perfect square form of:

So the given expression is factorized as follows:

Thus the factored form is:

answer

106 emergencies

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
