If the leading coefficient is negative, always factor out the negative.-x^2+5x-6​

Mathematics
1 answer:
vova2212 [387]3 years ago
7 0

Answer:

-1(x-2)(x-3)

Step-by-step explanation:

first we factor the negative:

-1 (x^2 - 5x +6 )

the next step, (if possible) is to guess 2 numbers that multiplied are 6

and added are -5

in this case is easy to see that those numbers are -2 and -3

The solution then is:

-1(x-2)(x-3)

If guessing the 2 numbers doesn't work, you need to complete the square

Find the value of x.
alukav5142 [94]

Step-by-step explanation:

The sum of the three angles in a triangle must be 180. Since this triangle has a right angle, we know that it is 90°, so the sum of the remaining two angles must be 90.

We can set up an equation for the two remaining angles to determine the value of x:

(x + 28) + x = 90

2x + 28 = 90

2x = 62

x = 31

PLEASE HELP <br><br> Find f(2) if f(x) = (x + 1)2.<br> a 9 <br> b 6<br> c 5
lys-0071 [83]

Answer:

b

Step-by-step explanation:

x = 2 in this situation, so plug in 2 for x.

f(2) = (x + 1)2

f(2) = (2 + 1)2

f(2) = (3)2

f(2) = 6

f(2) = 6. That means b is the answer.

Which of the following describes the parabola with the equation y = −x2 − 3x + 6?
seropon [69]

Answer:

C) The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).

Step-by-step explanation:

The axis of symmetry is x = − b/2a

= -(-3) / 2(-1)

= 3/(-2)

= -1.5

the vertex => x = -1.5

y= -(-1.5)²-3(-1.5)+6 =

-2.25 +4.5+6= 8.25
