Answer:
(a) x = -0.418 , -3.581
(B) c = 6.855, -1.855
Step-by-step explanation:
(A) We have given equation 
On comparing with standard quadratic equation 
a = 2, b = 8 and c = 3
So roots of the equation will be 
(b) 
a = 1, b = -5 and c= -14
So 
Answer:
26 * 26^8 = 26^9
Step-by-step explanation:
Here, we want to write 26 * 26^8 in exponential form.
26* 26^8 is same as 26^1 * 26^8
According to the first law of indices, we are going to add the powers together;
Thus, this gives ; 26^(1 + 8) = 26^9
Based on the information given, it can be noted that Tom will use 117 days to read the book.
How to solve a equation.
Based on the information given, we are informed that Tom starts to read a book with 490 pages today. Sundays he reads 25 pages and on all other days he reads 4 pages.
Let the number of days be represented by x. Therefore, the equation to solve the question will be:
25 + (4 × x) = 490
25 + 4x = 490
4x = 490 - 25
4x = 465
x = 465/4
x = 116.25
x = 117
Therefore, he'll use 117 days to read the book.
