Step-by-step explanation:
8.9x-5 and -6.8x+8
8.9-6.8 + -5+8
2.1x+3
<u>Factoring:</u>
This equation cannot be factored because its roots are irrational (as shown by solving with the quadratic formula). Also, to factor a quadratic equation, you need to find a pair of numbers whose product is equal to the c term (-5) and whose sum is equal to the b term (-6). There is no pair of numbers which satisfies this, further showing that the equation cannot be factored.
<u>Quadratic Formula:</u>
The quadratic formula is x=.
First, you need to find the a, b and c terms of your equation. They are 1, -6, and -5 respectively.
Now, you must plug in to the equation and solve for x. You must do so twice, once with a plus sign in the numerator and once with a minus.
The answers are 3+√14 and 3-√14.

Answer:
15h + 4
Step-by-step explanation:
5(3h + 2) - 6
Distribute
5 x 3h = 15h
5 x 2 = 10
rewrite equation
15h + 10 - 6
Subract
10 - 6 = 4
