A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you factor 18x squared plus 9x plus 2?

That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (-1 plus or minus one third itimes the square root of 7) divided by 4.x = -0.25 + 0.22047927592204922ix = -0.25 - 0.22047927592204922iwhere i is the square root of negative one.


Is 9x2-18x plus 9 a trinomial square?

Yes.


Solve x2 plus 18x plus 4 equals 0?

This quadratic equation which will have two solutions can be solved by completing the square or by using the quadratic equation formula.Completing the square:x2+18x+4 = 0(x+9)2+4 = 0(x+9)2+4-81 = 0(x+9)2 = 77x+9 = + or - the square root of 77x = -9 + or - the square root of 77If you're not too sure about the procedure of completing the square your maths tutor should be familiar with it.


Is this trinomial a trinomial square x2-18x plus 81?

x2-18x+81 = (x-9)(x-9) when factored


What number must you add t complete the square x2 plus 18x equals -13?

81. To complete the square, halve the coefficient of the x term (18/2 = 9) and add the square of this (92 = 81) to both sides: x2 + 18x = -13 ⇒ x2 + 18x + 81 = -13 + 81 ⇒ (x + 9)2 = 68


What number must be added to the polynomial to complete the square of x2 plus 18x?

81. To complete the square of x^2 + 18x, you take half the coefficient of the x term (half of 18 is 9), and square that number (9 squared is 81). To confirm this works, you can now factor x^2 + 18x + 81 and see that it factors as (x+9)(x+9), or (x+9)^2, a perfect square.


The square of 9 more than a number is equal to 9 more than a square of the number what is the number?

(x+9)^2 =x^2 + 9 X^2 + 18x + 81 = X^2 +9 18X + 72 = 0 18X = -72 X =- 4


What number must you add to complete the square x2 plus 18x equals 29?

If: x^2 +18x = 29 Then completing the square: (x+9)^2 -81 = 29 or (x+9)^2 = 110


Does 12 sq yrds equal a 18x 20 ft room?

18 feet x 20 feet = 360 square feet. There are 9 square feet in one square yard, so 360 square feet = 40 square yards, not 12 square yards.


Is 9x2-18x 36 a perfect square trinomial of the form A2-2AB B2?

false


Is 9X2-18X plus 36 a perfect square?

No 9xx-18x+36 9(xx-2x+4) xx-2x+4 (doesn't factor evenly)
