Answer:
x² - 10x + 21 = 0
Explanation:
The standard form of the quadratic equation is:
ax² + bx + c = 0
This means that we want to have all terms on one side and a zero on the other.
This can be done as follows:
x² - 10x + 16 = -5
Add 5 to both sides of the equation:
x² - 10x + 16 + 5 = -5 + 5
x² - 10x + 16 + 5 = 0
Combine like terms to get the final expression in standard form as follows:
x² - 10x + 21 = 0
Hope this helps :)
