Factor: 9x2 - 25.
First you have to solve the subtraction and in the next step you will factor it out.
Find a number that evenly divides each term of the expression.
The greatest common factor of 25 and 175 is 25.
It is: 5 that is a prime factor of 25
This quadratic expression can not be factored because its discriminant is less than zero.
p2
Answer: Apex ↓Ptotal = P1 + P2 + P3 + ...
16x2 - 25 = (4x + 5) (4x - 5)
Whatever equals 35.
(x - 5)(x^2 + 5x + 25)
(p-3q) (p-3q) =p2+3pq+3pq+9q2 =p2+6pq+9a2 this is answer hehehhe (jhaylotte)
First of all, you can only measure power factor of a three-phase load, provided that it is balanced load. The power factor can then be found by determining the cosine of the phase angle, using the following equation:tan (phase angle) = 1.732 ((P2-P1)/(P2+P1))...where P1 and P2 are the readings of the two wattmeters.
p2-2p = p(p-2) when factored
Nothing is a factor BY ITSELF; you can say that one expression is a factor OF ANOTHER EXPRESSION. IF you don't specify the other expression, the question is meaningless.
If you mean 5x^2 -125 then it is 5(x^2 -25) when factored
There is no factor of the expression in the question.
