Solve the equation 2x^{2}-12x-14=x^{2}-8x2x 2 −12x−14=x 2 −8x to the nearest tenth PLEASE HELP

x = 6.2 or -2.2

Step-by-step explanation:

Given:

2x² - 12x - 14 = x² - 8x

Collect like terms

2x² - x² - 12x + 8x - 14 = 0

x² - 4x - 14 = 0

a = 1

b = -4

c = -14

x = -b ± √b² - 4ac / 2a

= -(-4) ± √(-4)² - 4(1)(-14) / 2(1)

= 4 ± √16 -(-56) / 2

= 4 ± √16 + 56 / 2

= 4 ± √72 / 2

= 4 ± 6√2 /2

= 4/2 + 6√2/2 or 4/2 - 6√2/2

= 2 + 3√2 or 2 - 3√2

= 2 + 4.2426406871192 or 2 - 4.2426406871192

= 6.2426406871192 or -2.2426406871192

Approximately,

x = 6.2 or -2.2

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
