The probability would be 0.5
58.50 - 45 = 13.50
13.50 / 45 x 100 = 30%
answer: mark up 30%
1,203,567,489 one billion two hundred three million five hundred sixty-seven thousand four hundred eighty-nine
3x^2 + 3x - 6
First factor out the 3 in front of x^2:
3( x^2 + x - 2 )
Now we can look at the inside of the brackets, and find two numbers that, when multiplied, give -2, and when added, give +1. You will usually find them if you create a list of factors of the constant term (-2 in this case).
2 * -1 = -2
2 + -1 = 1
So the factorization becomes 3(x+2)(x-1)
It's 67/100 because a percent is out of 100 which is already simplified
