1 answer:
Answer:
Step-by-step explanation:
First, we need to set up the equation
To solve this, we have two options: factoring or using the quadratic formula. In this case, factoring will work, so we can use that
To factor, we need to find two numbers that add together to give you 3 and multiply to give you -28
In this case, these two numbers would nee to be -4 and 7
This means that our factored equation would be:
Now all we need to do is input the values of x that will give you 0. This means that the two solutions are

Answer:
Step-by-step explanation:
All that we have to do is add the 3 and 5 so it's basically like combining like terms. So the first blank is 8.
Now we add the x and the 5x which is 6x, all we're doing is adding the x's.
Now we do add the two negative 10 and 7. So what is -10 + - 7 we add them normally but we'll still have the negative in front of them. So it's -17.
