Well, "minus 6 x cubed minus y squared minus 3 x y" translates to:
[tex]-6x^{2} -y^{2} -3xy[/tex]
Then, if we insert the values for x and y, we get:
[tex]-6(-2)^{2} -(4)^{2} -3(-2)(4)[/tex]
When we distribute and multiply:
[tex]144-16-24[/tex]
And once we combine like terms:
104 is the answer
The given statement can be written in expression form as
[tex]-6x^3-y^2-3xy[/tex]
As the value of [tex]x=-2[/tex] and [tex]y=4[/tex] are given .
To find the value of expression at the given values of [tex]x[/tex] and [tex]y[/tex] , we have to insert the values into the expression
[tex] -6(-2)^3-(4)^2-3(-2)(4)[/tex]
Now solving by cubing and squaring the numbers
[tex]-6(-8)-16-3(-8)[/tex]
As negative negative is positive and positive negative is negative
[tex] 48-16+24[/tex]
Adding like terms and subtracting we get
[tex]72-16=56[/tex]
56 is the Answer
Hope this will help
