Answer:

3x^2-2+2x^2-6x+3=5x^2-6x+1

Factor: 5x^2-5x-x+1=5x(x-1)-1(x-1)=5x-1(x-1)

Step-by-step explanation:

If you have answer choices, the answer would be 5x2 − 6x + 1.

Here’s how the multiplication works:

Perform the multiplication just as you would for whole numbers.

When you’re done, count the number of digits to the right of the decimal point in each factor and add the results.

Place the decimal point in your answer so that your answer has the same number of digits after the decimal point.

Which two values of x are the roots of the polynomial below? <br> x^2+5x+11

In-s [12.5K]

Answer:

x = -5/2 + i√19 and x = -5/2 - i√19

Step-by-step explanation:

Next time, please share the possible answer choices.

Here we can actually find the roots, using the quadratic formula or some other approach.

a = 1, b = 5 and c = 11. Then the discriminant is b^2-4ac, or 5^2-4(1)(11). Since the discriminant is negative, the roots are complex. The discriminant value is 25-44, or -19.

Thus, the roots of the given poly are:

-5 plus or minus i√19

x = -----------------------------------

2(1)

or x = -5/2 + i√19 and x = -5/2 - i√19

You spin the spinner and flip a coin. Find the probability of the compound event.

Mademuasel [1]

Answer:

The probability of spinning an even number and flipping heads is 1/4

Step-by-step explanation:

You spin the spinner and flip a coin.

A spinner that has 1 of each number, 1-6

Total events =12

(1,H),(2,H),(3,H),(4,H),(5,H),(6,H)

(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)

We are supposed to find probability of spinning an even number and flipping heads

Favorable events : (2,H),(4,H)(6,H) = 3

Total events = 12

The probability of spinning an even number and flipping heads = $\frac{3}{12}=\frac{1}{4}$

Hence The probability of spinning an even number and flipping heads is 1/4
