Answer:
<u>-24x² + 7x + 6</u>
Step-by-step explanation:
- (2 - 3x)(3 + 8x)
- 6 - 9x + 16x - 24x²
- <u>-24x² + 7x + 6</u>
Answer:
1. The given equation does not have root at x = - 3.
2. (x - 3) (x + 1) (x² + 4) = 0
This curve will intersect twice the x-axis.
Step-by-step explanation:
1. If the right hand side of the equation ......... (1) becomes same as the left hand side by putting x = - 3, then only we can conclude that x = - 3 is a root of the equation.
But in this case .
Therefore, x = - 3 is not a root of the above equation (1).
2. The equation of the polynomial with roots 3, -1, 2i, and -2i is
(x - 3) (x + 1) (x - 2i) (x + 2i) = 0
⇒ (x - 3) (x + 1) (x² + 4) = 0 (Answer)
Therefore, the graph of the above curve will intersect twice the x-axis in a real coordinate plane, at x = 3 and at x = -1. (Answer)
Step-by-step explanation:
true equation when x is replaced by 2, and is a false ... is written in terms of P, R, and T.” In some cases, before using a formula it may be ... (2) a number line graph, or (3) interval notation.
They teach the kids to group these. So the one spot, ten spot and hundred spot are called ONES PERIOD. The thousands, ten thousands and hundred thousands are grouped in THOUSANDS PERIOD. so in other words the number 208 would be a ONES PERIOD. Now let's say the number was 208,256 then 208 would be in the Thousands Period.
X=2. You use substitution to put the y=3x-5 into 6x+3y=15.
So you get 6x+3(3x-5)=15
=6x+9x-15=15
add 15 on both sides to get the x's alone and add the x's together.
6+9=15 -- 15+15=30
15x=30
30/15 =2
x=2
