JordanYou must find two factors of -63, that add up to -18. Since the third term is negative, you write down:
(x + ___) (x - ___)
and then look for such a number. In this case, the solution is:
(x + 3) (x - 21)
Since the product of the constant terms is -63, and their sum is -18.

What is the correct classification of 18x?
18x is a monomial because it only has a single x.
Can you divide 18x by 2?
For any value of x, 18x divided by 2 is always 9x.
Application of special product and factoring?
Special product and factoring
Factor the trinomial 5x2-18x plus 9?
5x2-18x+9 = (5x-3)(x-3)
18x equals 6 solve for x?
x = 1/3
What is the x intercept of 18x plus 12y equals 72?
18x + 12y = 72 to get x-int. put y=0 18x + (12)(0) = 72 18x = 72 x = 4 your x-intercept is 4. this is the place where the line goes through the x-axis.
What is x equal to in the math problem 18x equals 198?
18x= 19818x/18 = 198/18x = 11
How do you solve x2-18x-40?
x=4 and x =7Improved Answer:-x2-18x-40 = (x+2)(x-20) when factored
How do you get 81-18x plus xsquared from (9-x)squared?
Because: (9-x)(9-x) = 81-18x+x^2
2X2 plus 18X equals 20?
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
What is the correct classification of 18x?
18x is a monomial because it only has a single x.
Solve the equation 6 x 1 18x?
The equation 6 x-1 18x can be simplified to the answer 112x.
How do you solve x 2-18x-4 equals 0 by completing the square?
x² - 18x - 4 = o x² - 18x = 4 x² - 18x + (18/2)² = 4 + (18/2)² x² - 18x + 81 = 4 + 81 (x - 9)² = 85 x - 9 = ±√85 x = 9 ±√85 x = 9 + √85 or x = 9 - √85 if you are still confused, i want you to follow the related link that explains the concept of completing the square clearly.
How do I combine like terms expression -16x plus 2 plus 18x?
-16x + 2 + 18x 'Like' terms are those which contain the same factor; in this case 'x' So taking -16x + 18x =. 18x - 16x = 2x So it becomes 2x + 2 NB The '2' , on its own is a constant, so is not a 'like' term. Similarly, something like 2x^3 + 3x^2 + x^3 - x^2 . The 'x^3' are like terms , and the 'x^2' are like terms, but 'x^3' is unlike to 'x^2'. So collecting like terms it would become 4x^3 + 2x^2 . When you do something like 2x^2(2x + 1) , this is NOT collecting like terms , but FACTORING. Hope that helps!!!!!
What is x2 equals 18x-80?
x2=18x-80 (im guessing you are trying to find x) x2-18x+80=0 (x-10)(x-8)=0 Therefore: x = 10, 8
Is this trinomial a trinomial square x2-18x plus 81?
x2-18x+81 = (x-9)(x-9) when factored
Can you divide 18x by 2?
For any value of x, 18x divided by 2 is always 9x.
