Question

Consider the expression:2×*2-×+4(a)what is the degree of the expression?(b)how many terms does the expression have?(c)find the value of the expression if ×=-2

Answer 1

a)`2x*2-x+4`

The degree of the expression is 1 since the highest power is 1.

b)`color(red)(" 2"x*"2")color(magenta)( - x)color(darkred)( " + 4"`

There are 3 terms as u can see above.

c)`2x*2-x+4`

When `x=-2`

`=>2(-2)*2-(-2)+4`

`=>-8+2+4`

`=>-2`

~Hope this helps! :)
