Subtract the second expression from the first. (3x^2+2x-1) - (x^2-3x+4)
Eva8 [605]

Step by step solution :

Step  1  :

Equation at the end of step  1  :


 ((3x2 +  2x) -  1) -  (x2 - 3x + 4)


Step  2  :

Trying to factor by splitting the middle term


2.1     Factoring  2x2+5x-5


The first term is,  2x2  its coefficient is  2 .

The middle term is,  +5x  its coefficient is  5 .

The last term, "the constant", is  -5


Step-1 : Multiply the coefficient of the first term by the constant   2 • -5 = -10


Step-2 : Find two factors of  -10  whose sum equals the coefficient of the middle term, which is   5 .

      -10     +     1     =     -9  

      -5     +     2     =     -3  

      -2     +     5     =     3  

      -1     +     10     =     9  



Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :


 2x2 + 5x - 5

Answer:

D

Step-by-step explanation:

Since x is squared, that's a non-linear equation because it's the only answer that, when graphed, doesn't form a straight line

Help!! WILL GIVE BRAINLIEST!!! What is the range of possible sizes for side x? Please explain about the rule as well.....
yaroslaw [1]

Answer:

0.2 < x < 11.8

Step-by-step explanation:

The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side, for it to form a triangle. So, we can set up 3 equations, x + 5.8 > 6, 5.8 + 6 > x, and x + 6 > 5.8. This solves out to x > 0.2, x < 11.8, and x > -0.2. We can disregard that last one, because a side can't be negative. Therefore, we know the possible range of values for x.

I hope I could be of help! Please give brainliest!
