88 -Apex ;)
The discriminant is 88.
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.
A polynomial of degree 0 is a polynomial without any variables, such as 9.
The discriminant is 9.
It is: 0
It is zero because: 182-4*9*9 = 0
The discriminant polynomial is always [ b2 - 4ac ]. In any given expression, it's a number. In this expression, the number is zero, indicating that the expression is a square.
The discriminant is 0.
Yes.
The discriminant is 88.
9x2 - 18x + 99(x2 - 2x + 1)==========
The discriminant of a quadratic ax2 + bx + c is b2 - 4ac; thus: the discriminant of -9x2 + 6x + 14 is 62 - 4 x -9 x 14 = 540
No 9xx-18x+36 9(xx-2x+4) xx-2x+4 (doesn't factor evenly)

Factors are: 9(x - 1)(x - 1) or (3x - 3)2, so yes, it is.
The discriminant is 88 which means that the given quadratic equation has two different solutions for x
