To complete the square you need to halve the linear coefficient -4/2, square it, 4, and add that value, giving you:

x^2-4x+4  and that is a perfect square equal to:

(x-2)^2

A​ whale-watching tour boat cannot operate if the total passenger weight is more than 7,200,000 grams. What is the maximum numbe
Scorpion4ik [409]

Answer:

80 Passengers

Step-by-step explanation:

A kilo gram is equal to 1,000 grams.

So 90 times 1000 is how much one passenger weighs in grams.

90,000 is one passenger.  

Divide

7,200,000/90,000=80

Your answer is 80 passengers

What are the solutions to 6x^2-5x-4=0
Zolol [24]
To factor a quadratic equation that has a leading coefficient, multiply the most and least significant coefficients together. In this case 6 * -4 = -24

We need to find two numbers that multiply to -24 and add to -5. We will split the middle term into these two numbers.

6x^2 -8x + 3x - 4 = 0

Here you can see that we split -5x into -8x and 3x.

Now we can factor by grouping. To do this, group the first two terms together and the last two terms together. Factor out whatever you can.

(6x^2 - 8x) + (3x - 4)

2x(3x - 4) + 1(3x - 4)

Notice that the second group had nothing to factor out so we just pull out a 1. Now we can rearrange the factored form according to the distributive property.

(2x+1)(3x-4) = 0

So the solutions are x = -1/2 and x = 4/3
