So, Im assuming the x2 is x², if so then the answer would be
G(4)
Ax²+24=8
we replace the x with the value of 4 since we're given the answer
A(4)²+24=8
and then we try and solve the equation, first we need to get rid of the square which is (4)² thats the same as 4*4 thats equal to 16, so our equation would look like this
A(16)+24=8
then we carry on to try an look for (A), we can start by getting the difference between 24 and 8 so we move it to the other side as a -24 and get this
16 (A) = 8 - 24
which would basically be by adding a -24 to both sides so we can get rid of the +24, and we get the same equation as above
16(A)+24 -24 = 8 -24
16(A) = -16
then we need look for (A) by dividing both sides to 16
16(A)/16 = -16/16
and we get that (A) = -1
so with that now we can look for the value of G(-4)
first we form our new equation with the value of A and the new value of G which is -4, now since we are dealing with a square it doesnt matter if (x) its positive or negative since it doesnt really affect the previous result (4)²=16 and (-4)²=16, but for the sake of it lets try to do it
G(-4)
A(-1)
ax²+24
so we replace with the values already obtained (A) and (x)
(-1)(-4)²+24
as stated before the
(-1)(16)+24
and all thats left is this
-16+24
and the answer to the question would be 8
