Putting values, we get,
Thus, the discriminant of the quadratic equation is -7.
If it is 20% off, then ur actually paying 80%
so an equivalent expression would be 0.80p
Answer: Rico is right.
(-1)(3x + 5)²
Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.
It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.
Then factor 9x² + 30x + 25 as
(3x + 5)²
Answer:
one half of two fifths of x would be equivalent to one fifth of x
