Before you use the quadratic formula, you have to make sure the equation itself is a quadratic and that a and b are not 0.
I don’t know all of them but the ones across 8 are the same as 8 so 1,4, and 6 are all 42° :)
Is it 4 times x or 4 to the power of x, if the first one then, 8x-24x. if the second then 8^-6x
Whers the rest of the problem
