4a^4 -2b^2 +40
a=2
b=7
4(2)^4 -2(7)^2 +40
PEMDAS is what your gonna use to solve this you go from right to left
First is P which is parentheses which is none
second is E which stands for exponents
4(32)-2(49)+40
now MD multiply or divide
128-98+40
now add or subtract
30+40
last one
70 this is your answer i hope

You can solve any further
2x - 6 = 14
Add 6 to both sides to isolate the x
2x = 20
Divide 2 to both sides since x is multipled to x
x = 10
To check your work plug 10 into the equation
2(10) -6 = 14
20 - 6 = 14
14 = 14
and it works
