Margarita [4]3 years ago

If this is just factoring, x^2 + x - 90 turns into this:
(x - 9)(x + 10)


If your trying to solve for x, we take the factored expression and set it equal to 0.
(x - 9)(x + 10) = 0

Set each binomial into two equations.
x - 9 = 0 and x + 10 = 0

Solve for x and we get two answers.
x = 9
x = -10

horrorfan [7]

Answer:

(1.2. - 4.7)

Step-by-step explanation:

On a coordinate plane, a line is drawn from point A to point B. Point A is at (7,-2) and point B is at (-8,-9).

Now, it is asked the x- and y-coordinates of point C, which partitions the directed line segment from A to B into the ratio 5:8.

So, the coordinates of point C are

[\frac{5 \times (- 8) + 8 \times 7}{5 + 8}, \frac{5 \times (- 9) + 8 \times (- 2)}{5 + 8}]

= [\frac{16}{13}, \frac{-61}{13}]

= (1.2. - 4.7) (Answer)

{Round to the nearest tenth}
