How can you factor each expression?
Some expressions can't be factorised, and you have to use other methods to solve the equation.
What is the quadratic expression for 108x2-102x plus 24?
108x2-102x+24 Simplified by dividing all terms by 6: 18x2-17x+4 When factorised: (9x-4)(2x-1) With a question like this using the quadratic equation formula will help.
What do you do with remainders in quadratic expressions?
Leave it the way it is. (by Stephen Hawking)
Is the foil method used for factoring quadratic equations?
Yes FOIL method can be used with quadratic expressions and equations
X2 plus 6x plus 8 equals?
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
When will you apply surds in real life?
You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.
How do you factor p2 plus 2p-7 equals 0?
The quadratic cannot be factorised. Its roots are irrational.

Does quadratic equation relate to science?
No, the quadratic equation, is mainly used in math to find solutions to quadratic expressions. It is not related to science in any way.

Yes FOIL method can be used with quadratic expressions and equations
R2 plus 10r plus 25?
The quadratic expression: r2+10r+25 = (r+5)(r+5) when factorised
What is 2(4x3-3x2-8x) completlely factored?
It is 2x*(4x^2 - 3x - 8). The quadratic cannot be factorised: it has no rational roots.
X2 plus 6x plus 8 equals?
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
How do you factor a quadratic equation without a b value?
A quadratic, of the form ax2 + c can always be factorised as a(x2 + c/a). It can be factorised into real linear factors only if c is negative. So suppose c = -d where d is positive. Then ax2 - d = a(x2 - d/a) = a*[x - √(d/a)]*[x + √(d/a)] The linear factors are rational only if d/a is a rational square.
What is 2x with the exponent 2 plus 3x plus 1. what is 7n with the exponent 2 plus 9n plus 2. what is 3x with the exponent 2 plus 8x plus 5. what is 7y with the exponent 2 plus 19y plus 10?
The first and third are quadratic expressions in x, the second is a quadratic expressions in n, and the fourth is a quadratic expressions in y. None of them are equations so cannot be solved.
