Solve for x. x2 − x − 12 = 0 a) x = −2 or x = 6 b) x = 2 or x = −6 c) x = −4 or x = 3 eliminate d) x = 4 or x = −3

D) x = 4 or x = −3

Step-by-step explanation:

x^2 − x − 12 = 0

Factor

What 2 numbers multiply to -12 and add to -1

-4*3 = -12

-4+3 = -1

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

Using the zero product property

x-4 =0   x+3 =0

x=4  x=-3

~

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
