Answer:

If you plug it all in you will get x=2 x=-3

Step-by-step explanation:

The quadratic formula is

-b+/-\sqrt-b^2-4ac all over 2(a)

your equation 2x^2+2x-12

you can label it

a=1      b=2               c=-12

If you plug it all in and solve you will get x=2 x=-3

Using radicals, write an equivalent expression for the expression y^{\frac{1}{5}}.
Blizzard [7]
All we want to do is use the formula...
x^{ \frac{a}{n} } =  \sqrt[n]{a^x}
In doing so we should get...
\sqrt[5]{y}
This is an equivalent expression however just the radical form of your given expression.

When dividing with polynomials, the goal is to determine how many times the dividend divides evenly into the?
kkurt [141]
Whether dividing constant terms or polynomials, we always have definitive terms when it comes to division. Suppose we say, 10x divided by 2. The dividend is the 10x and the divisor is the 2. In other words, the dividend is the number to be divided by the divisor, to obtain the answer called the quotient.

When dividing polynomials, your main goal is to be able to divide the dividend evenly into the <em>divisor</em>. For example, we divide x²+2x+1 by x+1. The first thing you're going to focus is, what term will completely divide the first term of the polynomial? That would be x. Why? Because when you multiply x with x+1, the product is x²+x. When you subtract this from the polynomial, the x² will cancel out. All you have to do is subtract x from 2x, yielding x. Then, you carry down the last term of the equation: +1. You do the steps again. The term that will completely divide x+1 by x+1 is 1. When you subtract the two, you will come up with zero. That means there is no remainder. The polynomial is divisible by the divisor. 
                          x + 1
                        ------------------------------------
                  x+1| x²+2x+1
                        - x²+x
                         ----------------------
                                 x +1
                               - x + 
                             ------------

One of the Same side angles of two parallel lines is 60° greater than the other. Find the two angles.
BARSIC [14]

Answer:

60,120

Step-by-step explanation:

We know that angles on the same side of the transversal always add up to 180 ( are supplementary)

Hence, taking one of the angles as x we get,

x+(60+x)=180

2x+60=180

2x=120

x=60

Hence, one angle is 60 degrees while the other 120 degrees
