where do you get stuck?
-6(-3)+8 = 18+8 = ?
the value of -6x+8= - when x is -3
the value of 6x+8= - when x is 3
-6(-3)+8 = 18+8 = ?
1. Polynomial: -6x+8.
a) For x = -3:
Replace x with -3 in the polynomial expression:
-6(-3) + 8
(Multiplying -6 by -3)
18 + 8
(Adding 18 and 8)
26
Therefore, when x is -3, the value of -6x+8 is 26.
b) For x = 3:
Replace x with 3 in the polynomial expression:
-6(3) + 8
(Multiplying -6 by 3)
-18 + 8
(Subtracting 18 from 8)
-10
Therefore, when x is 3, the value of -6x+8 is -10.
2. Polynomial: 6x+8.
a) For x = -3:
Replace x with -3 in the polynomial expression:
6(-3) + 8
(Multiplying 6 by -3)
-18 + 8
(Subtracting 18 from 8)
-10
Therefore, when x is -3, the value of 6x+8 is -10.
b) For x = 3:
Replace x with 3 in the polynomial expression:
6(3) + 8
(Multiplying 6 by 3)
18 + 8
(Adding 18 and 8)
26
Therefore, when x is 3, the value of 6x+8 is 26.
