When faced with an unknown variable in a maths problem, it is advised to find the subject formula and then use it to solve the equation to find the answer.
<h3>What is an Unknown Variable?</h3>
This refers to the type of variable in a given equation that has to be solved for because its properties or value is not known.
Hence, we can see that when faced with an unknown variable in a given math problem, it is better to find the subject formula, then input the value of this into an equation, to find the value of the variable.

Answer:
The standard form of the quadratic equation is x² + 3·x - 4 = 0
Step-by-step explanation:
The standard form of a quadratic equation is a·x² + b·x + c = 0
Given that the expression of the quadratic equation is (x + 4)·(x - 1) = y, we can write the given expression in standard form by expanding, and equating the result to zero as follows;
(x + 4)·(x - 1) = x² - x + 4·x - 4 = x² + 3·x - 4 = 0
The standard form of the quadratic equation is x² + 3·x - 4 = 0

Answer:
These numbers are the Powers of Two
Beginning with term #1 = 2, the next term is always 2 times the PRECEDING term.
Second term is two squared, or 2 times 2, namely four.
Third term, multiply that four by two, giving eight, also known as two cubed.
Fourth term is twice as much, namely sixteen.
Just keep on doubling!
