Solve for x:
x^2 + 10 x + 12 = 36
36 = 36:
x^2 + 10 x + 12 = 36
Subtract 12 from both sides:
x^2 + 10 x = 24
Add 25 to both sides:
x^2 + 10 x + 25 = 49
Write the left hand side as a square:
(x + 5)^2 = 49
Take the square root of both sides:
x + 5 = 7 or x + 5 = -7
Subtract 5 from both sides:
x = 2 or x + 5 = -7
Subtract 5 from both sides:
Answer: x = 2 or x = -12 Thus the Answer is A.

The probability of drawing a red face card from a deck of cards is 3/26
Explanation:
In a deck of cards, there are 6 red-faced cards.
Probability = No. of favourable events / Total no. of events
So, the probability of drawing a red-faced card is 6 out of 52 cards.
Thus, the probability of drawing a red face card from a deck of cards is 6/52 = 3/26.
