---- ----
x 2
@Mathematics

Answer 1

4x+6=2x2
2x2-4x-6=0
x2-2x-3=0

Answer 2

x = 3 or, -1

Answer 3

(x-3)(x+1)
x=3
x=-1

Answer 4

x^2 -3x+x-3=0
x(x-3) +1(x-3) = 0
(x-3)(x+1) = 0
therefore x = 3 or x = -1

Answer 5

explain the two ways to simplify \[\sqrt{320}\] and provide the simplified form.

Answer 6

1.cross multiply
2.equation:2(2x+3)=2x^2
3.slove:4x+12=2x^2
4x+12-2x^2=0
(x-3)(x+1)
x=3 & x=-1

:D

Answer 7

that's 320?

Answer 8

\[8\sqrt{5}\]

Answer 9

Yes

Answer 10

320 = 16 * 20 = 4^2 * 2^2 * 5
sqrt{320} = 8Sqrt{5}

Answer 11

Explain

Answer 12

very simple.
result: \[2x ^{2}-4x-6\]
values: x=3 and x=-1
