while excluding 0, the product and quotient is positive if operating between same sign, otherwise if we operating different sign will resulted negative.
It's a cube so x should also equal 6
<span>Multiply the number in the tens place of the bottom number by the number in hundreds place of the top number. Multiply 3 times 7 to equal 21. Add the 1 you carried to equal 22. You don't need to carry the 2 in 22, as there are no more numbers to multiply on this line, so you can just write it down next to the 6.</span>
<span>z2 – 2z – 35 = 0
2z - 2z = 35
0 = 35
No solution</span>
The answer of f(-2) is 42
