Answer:
<em>D. is zero</em>
Step-by-step explanation:
<u>Graph of the Parabola</u>
The quadratic function's graph is called a parabola. There is a clear relationship between the roots of the equation and the shape of the parabola.
If the equation has two real roots, the parabola has two x-intercepts. If the equation has only one real root, the parabola crosses the x-axis only once, and if the equation has no real roots, the parabola never crosses the x-axis.
If the equation of the parabola is
Then the so-called discriminant is
If the discriminant is zero, the equation has only one real root. The graph in the image only goes through the x-axis once.
Thus, the correct answer is
D. is zero
Answer:
x(x+5)[(x+5)² +3(x-1)]
Step-by-step explanation:
(x²+5x)(x²+13x+22)
Expand
(x²+5x) (x²+13x+22) by multiplying each term in the first expression by each term in the second expression.
x²x²+x²(13x)+x²⋅22+5x⋅x²+5x(13x)+5x⋅22
Simplify terms.
x⁴+18x³+87x²+110x
Answer:
It would be true
Step-by-step explanation:
3x-7=14, add 7 both sides, 3x=21, x=7, therefore it's true. Hope this helps!
