Write a polynomial function $f$ of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.
olganol [36]

Answer:

f(x) = x^{3} + 4x^{2} -7x^{} -10^{}

Step-by-step explanation:

The zeros of the polynomial function are given us as -5,-1,2

If the zeros of a polynomial function are α,β,ω, the polynomial function can be obtained using the expression below:

f(x) = (x - α)(x - β)(x - ω)

where α = -5, β = -1, and ω = 2

f(x)=(x-(-5) )(x -(-1))(x - 2) = (x+5)(x+1)(x-2)\\\\f(x)=(x+5)(x^{2} -2x + x -2) = (x+5)(x^{2}  -x-2)\\\\f(x)=x(x^{2}  -x-2)+5(x^{2}  -x-2)\\\\f(x)= x^{3} - x^{2} -2x + 5x^{2} - 5x - 10\\\\f(x)= x^{3} + 4x^{2} -7x - 10

<em>NB: To arrive at the answer, expand the brackets and after expansion, collect like terms to obtain the final answer</em>

What is 2.5 x 7/10 =? and how did you get the answers?
Ivan

Answer:

1.75 or  \frac{35}{2}

Step-by-step explanation:

2.5 * 7/10 is just like 2.5 * 0.7

so 2.5 * 0.7 = 1.75

You could also convert 2.5 to fraction which is 25/10

so you would have \frac{25}{10} * \frac{7}{10} = \frac{175}{100} reduced would  equal \frac{35}{2}

How this helps you! :)

Could you please mark this answer as brainiest?

It would help me!

Thank you!

Identify the property used in each step of solving the inequality . 7x+4&lt;46
ExtremeBDS [4]

For this case we have the following inequality:

7x + 4

Subtracting 4 from both sides of the inequality we have:

7x

Dividing between 7 on both sides of the inequality we have:

x

Thus, the properties used were:

Subtraction property

Division property

Answer:

Subtraction property

Division property
