There are two ways to solve this, by factoring or the quadratic formula. I recommend factoring if possible because it is faster.
-18x2 + 24x + 10 = 0
The first thing I see, is that I should factor out a -2 to make this problem more workable.
-2(9x2 - 12x - 5) = 0
The -2 is now irrelevant, so I can cancel it and factor what remains.
(3x + 1)(3x - 5) = 0
Now solve each separate equation for x to get two answers.
3x + 1 = 0, 3x = -1, x = -1/3
3x - 5 = 0, 3x = 5, x = 5/3
ANS: x= -1/3, 5/3
What else can I help you with?
7x plus 10 equals 31 x equals?
7x+10=31x so 10=31x-7x or 10 =24x in which case x=10/24 or 5/12
-4 plus 10 equals?
-4 plus 10 equals 6.
If x equals 10 and y equals 10 then 9x plus 8y equals?
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
WHAT DOES 100 equals 3x plus 6x plus 10 equals?
x=10
12 plus 10 plus 11 equals?
12 + 10 + 11 equals 33
What does -10 plus 10 equal?
-10 plus 10 equals 0.
What is 39 plus 10 plus 10 plus 2 equals?
61
How would you get 12 is you used 10 four times?
10 plus 10 equals 20 20 divide by 10 equals 2 2 plus 10 equals 12
What plus what plus what equals 30?
10 + 10 + 10
What is the answer to A plus 6 equals 10?
A equals 4 because 4 plus 6 is 10 or 10 minus 6 is 4.
What is 19 plus 10?
19 plus 10 equals 29.
What is 2n plus 10 equals n plus 20?
10
