Factorise the quadratic equation this way :)

Reptile [31]3 years ago

Answer:

y=2(x+2)(x+3)

Step-by-step explanation:

First, we need to factor the right side:

y=2(x^2+5x+6)

Now, we can have an incomplete equation like this:

y=2(x+_)(x+_)

In the blanks, we need to fill out numbers that add to be 5 and multiply to be 6. What are factors of 6? 6 and 1, 2 and 3. Do 6 and 1 add to be 5? No. Do 2 and 3 add to be 5? Yes!

So, our factored form is

y=2(x+2)(x+3)

The product of -2 and a number minus six is greater than-18
Debora [2.8K]

Answer:

x<6

Step-by-step explanation:

The Product(multiplication) of -2 and a number(x) minus(-) six IS(=) greater than(>) -18.

Which gives you: -2x-6>-18

First step is to get the -2x by itself so we add 6 to both sides.

-2x>-12

We then want to get x by itself so we divide by -2 on both sides. Don't forget to flip the inequality sign because we are dividing by a negative.

x<6

What is -4(-4+3)+2 squared. use order of operations.
sineoko [7]
To solve this, first solve the part of the equation in parentheses: (-4+3) = -1. Then multiply using the exponent 2 squared is 2×2 which is 4. Now the equation is -4(-1)+4. Next you multiply, -4(-1)=4. You are then left with 4+4 which equals 8.

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

Mars is 400 million kilometers away, its furthest distance from Earth?
Sergio [31]

Answer:

Mars is the fourth planet from the sun. It has been a favorite object of skywatchers for centuries and of space explorers for decades. The distance to Mars depends on when you measure it, and which vantage points you're considering. Just how far away is the Red Planet?

Hope this helps!
