Question

x^(2)10^x-2x(10^x)=3(10^x)
solve equation..

Answer 1

10^x(x^2 -2x -3) =0
x=1,-3

Answer 2

can you walk me through it please

Answer 3

that was wrong

Answer 4

x^(2)10^x-2x(10^x)=3(10^x)

Answer 5

Factor out 10^x
then solve like any other quadratic equation

Answer 6

so 10^x(x^2-2x)=3(10^x)?

Answer 7

Bring LHS and RHS to same side and solve quadratin x^2 -2x -3

Answer 8

bring what?

Answer 9

all terms to one side

Answer 10

so 10^x(x^2-2x-3)=0

Answer 11

?

Answer 12

Yep now you have it factorize quadratic
and 10^x gives no roots as it is always greater than zero

Answer 13

so final answer is -1,3

Answer 14

1,-3

Answer 15

no -1,3 ...why u get 1,-3?

Answer 16

YEah it was a test
