X² + c is actually a quadratic function.
And x² + c = 0, it usually has two zeros which are solutions.
But for when c = 0,
x² + c = 0
x² + 0 = 0
x² = 0
Taking the square root of both sides.
x = 0. Here it only has one zero.
So the function x² + c, only has one root for c = 0.
Answer:
(d) (4x² +7)(x -3)
Step-by-step explanation:
This polynomial can be factored by factoring pairs of terms.
= (4x³ -12x²) +(7x -21)
= 4x²(x -3) +7(x -3)
= (4x² +7)(x -3)

<em>Additional comment</em>
The answer choices suggest we're not interested in irrational or complex factors. The quadratic (4x² +7) could be factored into linear terms involving irrational complex numbers. The form for "difference of squares" would be used for the purpose.
Answer:
did u ever find out the answer ?
Step-by-step explanation:
1. is D) 4/3 To find the slope we will insert the numbers into this formula: y2 - y2 / x2 - x1, so... 1 + 3/ 1 + 2 (the negatives canceled each other out)
now simplify and it becomes 4/3
so ur answer to 1. is D) 4/3
2. Plot this one...it rly helps...then use the slope to find the point ur looking 4, the answer is C) -2
3. The answer is B) -2
Hope that helps u out!! :)
0.3x = 48
So x is 48/0.3
Therefore, 0.5 times 48/0.3 is the answer
