What is the factorization of 3x^2 – 8x + 5?

Step-by-step explanation

Step 1: multiply the coefficient a and the constant c. Given that the general expression of a parabolic equation is ax^2+bx+c

3*5=15

Step 2: examine the coefficient b and try to find 2 numbers which you can multiply to get 15, add or subtract and get - 8

In this Case: - 3*-5=15 and - 3+(-5)= - 8

Step3:

You separate the equation in terms of the two factors you have found

3x^2-3x-5x+5=0

Step 4:Factorise

3x(x-1)-5(x-1)=0

(3x-5)(x-1)=0

The top speed of a zebra is 0.36 feet per second than a wildebeest.

First, we can start by subtracting the top speed of each animal. 64.4 - 64 = 0.4 The zebra is 0.4 km/h faster than the wildebeest.

Now, we just have to move from km/h to feet per second. To start, we need to divide by 3600 because there are 3600 seconds in an hour. Next, multiply by 0.62137 because there are 0.62137 km per mile. Finally, convert the miles to feet by multiply by 5280 (the number of feet per mile).

The result is a speed of about 0.36 feet per second.
