2x² + 4x - 16 = 0
2(x²) + 2(2x) - 2(8) = 0
<u>2(x² + 2x - 8)</u> = <u>0</u>
2 2
x² + 2x - 8 = 0
x = <u>-(2) ± √((2)² - 4(1)(-8))</u>

Answer:
w = 2/3
Step-by-step explanation:
The product of a number and 6 is 6w.
6w = 4
Dividing both sides by 6 results in w = 4/6, or w = 2/3
4x-10=6x+4; -10=2x+4; -14=2x; x=-7
Answer:
x = - 4
Step-by-step explanation:
First do distributive property
5x-15=10x+5
then add 15
5x=10x+20
-10x
-5x=20
divide 5
x=-4
Answer:
Step-by-step explanation:
hello :
- 2u + 12u ² + 8 - u ^ 9 = -1u ^ 9+12u² -2u+8...standard form
the degree is 9 and leading coefficient is -1
