What is the factored form of 2x^2-7x+6

Mathematics
1 answer:
Xelga [282]3 years ago
6 0

Answer:

(2x - 3)(x - 2).

Step-by-step explanation:

Factor:  2x^2 - 7x + 6

Use the ac method to do this:

Multiply the leading coefficient by the last term:

2 * 6 = 12.

Now we want 2 numbers whose product is  12 and whose sum is -7.

That would be -3 and -4 so we write:

2x^2 -4x - 3x + 6

Now factor by grouping:

= 2x(x - 2) - 3(x -2)

(x - 2) is common to the 2 parts so we have:

 (2x - 3)(x- 2).

The Chang family is on their way home from a cross-country road trip. During the trip, the function D (t) = 3260 - 55t can be us
Lilit [14]

Answer:

See below.

Step-by-step explanation:

D(t) = 3260 - 55t

The function that shows their distance from home as a function of time shows that they started 3260 miles from home and are driving at 55 miles per hour.

part a:

D(12) = 3260  55(12)

D(12) = 3260 - 660

D(12) = 2600

Interpretation: After 12 hours of driving home, they are 2600 miles from home.

part b:

D(t) = 2490

3260 - 55t = 2490

-55t = -770

t = 14

Interpretation: When they are 2490 miles from home, they have driven for 14 hours.
