What is the value of x in the equation 2x^2 +5x=12
*show work pls thankyo

Step-by-step explanation:

you can factor this pretty straight forward

2x^2 +5x=12

2x^2 +5x-12=0

Use  FOIL

(2x-3)(x-4)=0

then solve for each part separately, b/c if either side is zero the whole thing is zero

2x-3 = 0

2x = 3

x = 3/2

then

x-4=0

x = 4

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
