First, you need to acquire delta i m sorry is b squared minus 4ac. If delta is greater than cero, the polynomial has two solutions, if it is less, the polynomial has actually no actual solutions and if that is the same, it has actually one solution.Although the is just for second grade ecuations

One have the right to determine the variety of roots by see the degree of the provided polynomial.

You are watching: How can you quickly determine the number of roots a polynomial will have by looking at the equation

Step-by-step explanation:

The number of roots deserve to be recognize by just seeing the greatest power that the given equation.

Example,

1) because that the equation

*

here, the highest possible power the equation is one. So, it will have one root.

Lets check it by leveling

*

Hence, the equation has actually only one root namely x = 4.

2) consider a quadratic equation,

*

here, the greatest power the equation is two.So, that will have actually two roots.

Lets check it by simplify using middle term splitting method,

*

*

*

*
or
*

thus, the equation has two roots.

Hence, one deserve to determine the variety of roots by see the degree of the given polynomial.

Given: x + y = 6.
jolli1 <7>
X + y = 6when x = -15-15 + y = 6y = 6 + 15y = 21.....solution is (-15,21)when x = -6-6 + y = 6y = 6 + 6y = 12...solution (-6,12)when x = -1-1 + y = 6y = 6 + 1y = 7...solution is (-1,7)so ur rebab.net is : (-15,21) , (-6,12) , (-1,7)

A. Compose the equation ax + b = c in regards to x.
Oksanka <162>

rebab.net:

x=c/a-b/a

Step-by-step explanation:

ax+b=c

1) Subtract b native both sides:

ax=c-b

2) divide both political parties by a:

x=c/a-b/a

*

Step-by-step explanation:

We have actually been provided that a square pyramid has a base through a side size of 7.5 feet and lateral faces with heights of 16 feet. We space asked to find the surface area of the square pyramid.

We will certainly use surface ar area the square pyramid to solve our given difficulty as:

*
, where,

a = length of every side the base,

h = height of lateral face.

Help plz i will certainly rate

Hello!To start off, remember the supplementary angles space angles that include up come 180 degrees. Therefore, we know the sum of these two angles will certainly be 180 degrees.So, we must add the two angles together, then set it same to 180 and also solve because that x!(X)+(17x+72)=180Now, fix for x!18x+72=180Subtract 72 from every side 18x= 108Divide by 18 to obtain xX=6Therefore, the measure of the very first angle (x) is 6 degrees.Now, substitute that number right into the “x” in the 2nd angle.(17*6)+72= 174 degreesTherefore:The first angle is 6 degreesThe 2nd angle is 174 degreesI hope this helped!
