Answer:
If your quadratic equation it is in the form of x^2+bx+c=0 (in other words, if the coefficient of the x^2 term=1), it's possible (but not guaranteed) that a relatively simple shortcut can be used to factor an equation. Find two numbers that both multiply to make C and add to make B.
Step-by-step explanation:
Answer: B
Step-by-step explanation: because 2/3 = 0.66666, So 0.66 is greater than 0.6 Hope this helps. pls mark me brainliest :)
For quadratic
.. ax^2 +bx +c = 0
the discriminant is
.. d = b^2 -4ac
You have
.. a = 2
.. b = -5
.. c = 7
so the value of the discriminant for your equation is
.. (-5)^2 -4(2)(7)
.. = 25 -56
.. = -31
Because the discriminant is negative, the roots of the quadratic are complex.
Reasoning: this is the usual interpretation of the sign of the discriminant. It derives from the fact that the square root of the discriminant is part of the roots of the quadratic. That part will be imaginary when the discriminant is negative.
_____
The graph shows there are no real roots.
Sequence
8 - 7 = 1
15 - 8 = 7
23 - 15 = 8
38 - 23 = 15
For more sequences
38 + 23 = 61
Then
61 + 38 = 99
And so on the sequence continue
A. 0.07
Explaination:
if you were to say these are money.
0.59 would be 59 cents. 0.07 would be 7 cents.
59 is greater then 7 cents. so A is your answer
