Question

x2+5x=14

Answer 1

x^2 +5x -14 = 0

[(-b \pm \sqrt{b ^{2}-4*a*c})/2*a\]

1 = a
5 = b
14 = c

Answer 2

i dont get it thoe.

Answer 3

x^2+5x=14

factor out an x

x(x+5) =14

do you know how to solve that.

Answer 4

okay it will be x=9 right

Answer 5

or am i wrong.?

Answer 6

and x = 14

Answer 7

so how could i do it.?

Answer 8

x^2+5x=14

x(x+5) = 14

x = 14

and

x + 5 = 14

x = 14-5

x = 9

Answer 9

so i was right.

Answer 10

yes, but you also have to have x = 14. there are two solutions.

Answer 11

ooh okay so thats not it.? because i subracted 14 and 5.

Answer 12

\[x^ 2+5x- 14= 0 \\ x^ 2-2x + 7x -14= 0 \\ x (x + 7) -2 (x + 7 ) = 0\\ (x + 7) (x +2) \\\\ x = 7, \ \ \ x = -2\]
