Write that in standard form first

x4 - 4x3 - 15

The leading coefficient is the term that has the largest exponent so it will be x or 1

I need help ASAP -2x^2+x 9-25x^2+8x X^5+x^3-x^2-1

nika2105 [10]

Answer:

For $-2x^2+x$ , Leading coefficient is -2, Degree is 2, Constant term is 0

For $9-25x^2+8x$ , Leading coefficient is -25, Degree is 2, Constant term is 9

For $x^5+x^3-x^2-1$ , Leading coefficient is 1, Degree is 5, Constant term is -1

Step-by-step explanation:

Given:

Polynomials:

$-2x^2+x\\9-25x^2+8x\\x^5+x^3-x^2-1$

To find: leading coefficient, constant term and degree

Solution:

Leading coefficient is the coefficient of the variable with the highest power.

Degree is the highest power of the variable.

The term of degree 0 is the constant term of a polynomial.

For $-2x^2+x$ ,

Leading coefficient is -2

Degree is 2

Constant term is 0

For $9-25x^2+8x$

Leading coefficient is -25

Degree is 2

Constant term is 9

For $x^5+x^3-x^2-1$

Leading coefficient is 1

Degree is 5

Constant term is -1

Find the value of x.

andre [41]

The triangle is an isosceles triangle because of its degrees. A triangle consists of 180 degrees therefore, 180-90-45 simply makes it 45 matching the other side.

So we can assume that side b is also equivalent to side a. Here we use the pythagorean theorem to find x

a^2 + b^2 = c^2
5^2 + 5^2 = c^2
25+25=50

The square root of 50 is 7.1
x= 7.1
