You can easily factor this:
2x2 + 3x = 0
x(2x + 3) = 0
Separate this into two equations, one for each solution:
x = 0
2x + 3 = 0
2x = -3
x = -3/2
So the two solutions are 0, and -3/2.

86.26- Nearest hundredth.86.3- Nearest tenth.86- Nearest whole number.
0.164 is zero plus 1 tenth plus 6 hundredths plus ... So, rounded to the nearest hundredth, the number is 0.16
23.15 + 45.78 = 68.93 That is already at the nearest hundredth, so it does not need any further rounding.

It's an incorrect statement. 5 plus 6 equals plus 11. Also, pi R round, cornbread R2 .

To round off to the nearest integer... double a = {some value}; a = (int) (a + 0.5); To round off to the nearest hundredth... double a = {some value}; a = (int) (a * 100. + 0.5) / 100.; These are just two examples.
6.50 to the nearest hundredth (4.685 & 1.815)
23.15 + 45.78 = 68.93 That is already at the nearest hundredth, so it does not need any further rounding.
Quadratic formula gives roots as 1.53 and 10.47 (to nearest hundredth.)
Estimating is just an educated guess. For example, if you have to solve the problem 102.17 plus 266.18, you would make an educated guess. An educated guess would be 100+ 270 which equals 370. When you are rounding, you will usually get instructions to round a certain number. It is knowing the exact value, but finding the nearest whole number. For example: Round to the nearest hundredth 4.6781 If you are rounding to the nearest hundredth, you are trying to round the number 8, since it is in the hundredths spot. To round 8, look at 1. Is it greater than 5? If the number is greater than 5, round the number up by 1. If the number is smaller than 5, the number remains the same.

You cannot.
14x + 11
This simplifies to x2 + 10x + 17 = 0 which has no solution in integers. Quadratic formula gives roots as -2.17 and -7.83 to the nearest hundredth. If the original equation had been "equals 0" rather than "equals 8", there would have been only one root: x = -5
