Factor trinomial by grouping : 10x^2-9x+2​

Mathematics
1 answer:
Angelina_Jolie [31]3 years ago
8 0

Answer:

(2x - 1)(5x - 2)

Step-by-step explanation:

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term, that is

product = 10 × 2 = 20 and sum = - 9

The factors are - 5 and - 4

Split the middle term using these factors

10x² - 5x - 4x + 2 (factor the first/second and third/fourth terms by grouping )

= 5x(2x - 1) - 2(2x - 1) ← factor out (2x - 1)

= (2x - 1)(5x - 2)

Please help! Find the equation of the line and I will mark as brainliest IF answer is right. <3
Hoochie [10]
<h3>Answer:  y = (3/4)x + 13/4</h3>

This is the same as writing y = 0.75x + 3.25

slope is 3/4 = 0.75

y intercept is 13/4 = 3.25

==========================================================

Explanation:

One marked point on this line is (-3,1)

Another point is at (1,4)

Let's find the slope of the line through these two points.

m = (y2-y1)/(x2-x1)

m = (4-1)/(1-(-3))

m = (4-1)/(1+3)

m = 3/4

m = 0.75

Now let's use point slope form to find the equation of the line

y - y1 = m(x - x1)

y - 1 = 0.75(x - (-3))

y - 1 = 0.75(x + 3)

y - 1 = 0.75x + 2.25

y = 0.75x + 2.25 + 1

y = 0.75x + 3.25

If you wanted, you can convert those decimal values to fraction form

  • 0.75 = 75/100 = 3/4
  • 3.25 = 325/100 = 13/4

That means the equation

y = 0.75x + 3.25

is the same as

y = (3/4)x + 13/4
