10 points! How do I factor 8x^2-26x+15
Rufina [12.5K]
<h3><u>(2x - 5)(4x - 3)</u></h3>

The AC method, also known as splitting the middle, can be shown like this:

8x^2 - 26x + 15

<em><u>Check factors of 120.</u></em>

1 * 120

-1 * -120

2 * 60

-2 * -60

3 * 40

-3 * -40

5 * 24

-5 * -24

6 * 20

-6 * -20 (these factors, when added together, are equal to the middle term, and thus splitting the middle term is possible.)

<em><u>Split the middle term.</u></em>

8x^2 - 6x - 20x + 15

<em><u>Group in terms of 2.</u></em>

(8x^2 - 6x) - (20x + 15)

<em><u>Factor each binomial.</u></em>

2x(4x - 3) - 5(4x - 3)

<em><u>Rearrange the terms.</u></em>

(2x - 5)(4x - 3)

Polynomial Functions in context. a. A baseball is struck such that its position on a plane perpendicular to home plate can be de
Brums [2.3K]

The position of the ball when it is at its highest point is 121

<h3>Polynomial function</h3>

Given the polynomial function expressed as y = -1/250(x - 175)^2 + 121,

The velocity of the ball at the maximum point is zero. Hence;

dy/dx = -1/125(x-175)

Equating to zero;

0 = -1/125(x - 175)

x = 175

Substitute into the function to get the maximum height

y = -1/250(175 - 175)^2 + 121,

y = 121

Hence the position of the ball when it is at its highest point is 121
