This is a difference of two square, so you can apply the factoring rule for the difference of two squares.
There is no general conversion, since they measure different things (volume versus mass). You need to know the density of a specific material to do the conversion for that material, and apply the formula: mass = volume x density
Apply the formula of percent increase,which is : new value - old value / old value so, your question is what percent increase is 12 to 18, here 18 is the new value and 12 is the old value, now apply to the formula: percent increase= 18-12 / 12 = 0.5 now to get the percent multiply by 100 , 0.5*100 = 50% So, the percent increase 12 to 18 is 50%.
To calculate income tax, one should sum up the totals of all the taxable income and subtract from it the personal allowance and any other tax free allowances. After that, one should apply the rate of tax on the resultant value to find out the income tax payable.

Yes, simply treat the middle coefficient as 0.
The mathematical principles applied to each Quadratic Equation in Standard Form include factorization or factoring, variation(correlation of variables), monomial rules, domain and range.
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.
I suggest you apply the quadratic formula (a = 2, b = -4, c = -1).
You can combine equivalent terms. You should strive to put the equation in the form ax2 + bx + c = 0. Once it is in this standard form, you can apply the quadratic formula, or some other method, to solve it.
To answer a physics question using the quadratic formula, first identify the equation that represents the problem. If the equation is in the form of ax^2 + bx + c = 0, you can apply the quadratic formula: x = [-b ± sqrt(b^2 - 4ac)] / 2a. Solve for x using this formula to find the solutions to the equation, which may represent physical quantities such as time, distance, or velocity.
Find one factor by substituting in values, then use long division. You can then apply the quadratic formula to the result - or factorise it by sight, of course
Factoring rates apply to the practice of businesses selling receivables at a discount to a factor, who then collects the funds. The factoring rate is the amount of the discount at which the receivable is purchased.
The usual rules for "order of operation" apply. Don't forget that the square root of a negative number is an imaginary number. As an example, the square root of -9 is 3i (that is, the square root of +9, times the "imaginary unit").
Assuming that "x2" means x squared (x^2): x^2 - 4x - 32 = 0 factoring* (x-8)(x+4) = 0 So the roots are 8 and -4. Sorry I'm not sure what you mean by "symbolic answer." *If you don't see how to factor this trinomial, you can still apply the quadratic formula to get the same answer without being "clever."
