Construct an equation that has n = 6 as its solution. Use n on both sides of the equation.

nevsk [136]

Answer:

See Explanation

Step-by-step explanation:

Required

Determine any equation where n = 6

$n = 6$

Add n to both sides

$n + n = 6 + n$

$2n = 6 + n$ ----- This is 1 equation

$n = 6$

Multiply both sides by n

$n * n = 6 * n$

$n^2 = 6n$ ----- This is another

$n = 6$

Add 5n to both sides

$n + 5n = 6 + 5n$

$6n = 6 + 5n$ ---- This is another

Subtract 10 from both sides

$6n - 10 = 6 - 10 + 5n$

$6n - 10 = -4 + 5n$

$6n - 10 = 5n - 4$ --- This is another

You can have as many equations as possible

Explain why x and 4x - 10 are factors of the expression x(4x - 10)3 rather than terms of the expression. What are the terms of t

andriy [413]

Solution :- Let p(x) be the polynomial such that

$p(x) = x(4x-10)^3\\\text{and let f(x) be another polynomial such that }\\f(x)=4x-10\\\text{To find , Put } f(x)=0\\\Rightarrow4x-10=0\\\Rightarrow4x=10\\\Rightarrow x=5/2\\\text{Now substituting value of x in p(x),we get}\\p(x)=\frac{5}{2} .(4(5/2)-10)^3\\\Rightarrow\frac{5}{2}.(10-10)^3=0\\\text{Similarly let g(x)=x ,we get x=0 by putting g(x)=0}\\\text{now f(x)=0 for x=0}\\\text{So by Factor theorem f(x) and g(x) are the factors of polynomial p(x)}\\$

$\text{Now} p(x) = x(4x-10)^3\\=64x^4-480x^3+1200x^2-1000x\\\text{so the terms of terms of } p(x) \text{are} 64x^4,-480x^3,1200x^2,-1000x\\\text{here, by using Factor theorem x is a factor of all the terms but 4x-10 is not. }$
