n2 + 11n + 18 = n2 + 2n + 9n + 18 = n(n+2) + 9(n+2) = (n+9)*(n+2)
n2 - 11n - 26what two factors of - 26 add up to - 11?(n + 2)(n - 13)===========
To factorize the quadratic expression x^2 + 7x + 12, we need to determine two numbers that multiply to give us 12 and add up to 7. In this case, the numbers are 3 and 4. Therefore, the factored form of the expression is (x + 3)(x + 4).
Let's say y1, y2, and y3 are zeros. Set up an expression like this (x-y1)(x-y2)(x-y3) [This is factored form] and then multiply carefully. That works with any number of roots. If 0 is a root, add an x by itself to the beginning of the factored form expression. Also, imaginary roots come in twos. Therefore, if given i as a root, you need (x-i)(x+i). If you have something in x + yi form for a root, you'll need the complex conjugate. That would make (x-(a+bi))(x-(a-bi))
If you're looking to factor this expression, then you need to find two values that add up -20, and which multiply to make 4. Unfortunately, no such terms exist, so this expression can not be factored.
x^2 + 7x + 10 Since the 'x^2' term has a coefficient of '1' ( no number), then we look at the constant (10). We need two numbers that multiply to '10' and add to '7'. They are '5' & '2' Hence setting up brackets ( x 5 )(x 2) We note in the quadratic expression all the terms are positive(+) so plus(+) sign go in . ( x + 5)( x + 2) Factored Done!!!!

It means - Look at the expression. - If necessary, copy it to your scratch paper. - Using any method you need, find the factors of the expression. - Once you have the factors, write them on the test or homework sheet.

We don't know what the question is. (13 + 13x) isn't an equation, so it doesn'timply a question, and doesn't need a solution. It's an "expression", and its value(the number it's equal to) depends on what 'x' is at the moment.Maybe you got this as a homework question, and the assignment was: "Factor this expression."If that's the question, then here's the factored form:(13 + 13x) = 13 (1 + x) .It's important to understand that this isn't the 'answer' to anything.It's just a different way to write the same expression.
first of all you need to simplify it in the form of a+b
Does it look like I fing care Jesus
It can be factored to: 4(x-1)
If you're asked to simplify an expression, you need to expand all brackets if there are any, and collect all like terms. If the question is a fraction you have to give the answer in its simplest form
to find the value of an expression, you need to
