Answer:
double, real root x = -4
Step-by-step explanation:
Please use " ^ " to indicate exponentation: 2х^2 + 8х = х^2 - 16.
Combine like terms:
х^2 + 8х = - 16.
Re-write in the standard form for a quadratic:
х^2 + 8х + 16 = 0
Recognize that this is the square of the binomial x + 4:
х^2 + 8х + 16 = 0 => (x + 4)^2 = 0
Solving this last result for x yields the double, real root x = -4.
Answer: C
Step-by-step explanation: I just know the answer
Answer:
<u>D. Taylor correctly found the distance between –4 and 45, but this number represents the total distance the team moved in both directions, not the team’s total gain.</u>
Step-by-step explanation:
The team only ended up gaining the 45 yards on the second play and had gained -4 on the first play. 45-4≠49, but the total distance between -4 and 45 is 49.
ANSWER
EXPLANATION
The given product is:
We expand using the distributive property to obtain:
Extract the perfect squares to get:
Expand further to get;
This simplifies to,
(2x-3)(x+4) —> x= 3/2 x= -4
