find the value of the polynomial 8x - 6 when x = 1 and when x = -1
8(1) - 6= 2
8(-1) - 6=
-8 -6 = is the answer -14 or -2
-8 -6 = -14
To find the value of a polynomial for a specific value of x, you need to substitute that value into the polynomial expression and evaluate it.
For the polynomial 8x - 6, let's substitute x = 1:
8(1) - 6
= 8 - 6
= 2
So, when x = 1, the value of the polynomial 8x - 6 is 2.
Now let's substitute x = -1:
8(-1) - 6
= -8 - 6
= -14
So, when x = -1, the value of the polynomial 8x - 6 is -14.
