The sum of a number and its square is 42. Which equation can be used to find the two numbers for which this is true?
O x^2+ x = 42
OX^2 + 2x = 42
Ox^2 + x + 42 = 0
O X^2 + 2x + 42=0

Respuesta :

Answer:

The 1st option is true

Step-by-step explanation:

the number is x, the square of it is x² (x*x), they are just added up and together equal to 42

Option 2 has unnecessarily 2 times the number in the equation

Option 3 would mean the mentioned sum would equal -42 if we rewrite the equation

Option 4 has both error mentioned

(would really, reallly appreciate the brainliest)

Answer:

The answer is the first one, [tex]x^{2} + x + 42[/tex]
