Explanation:
Answer:
64
Explanation:
The question is incomplete without the expression that would be used to find the constant necessary to make a perfect square trinomial.
I would show you how to find the constant necessary to make a perfect square trinomial using the expression below:
x² - 16x + c
The expression above is in the form of a quadratic: ax² + bx + c
Where a = 1, b = -16, c = constant
First thing we do, is to square half the coefficient of x
Coefficient x above = b = -16
square of half the coefficient of x = (-16/2)²
Expand it, we have = -16/2 × -16/2 = 8×8 = 64
Replace the constant with 64
x² - 16x + 64
b/2 = -16/2 = -8
(x - 8)² will give a perfect square trinomial
Therefore the constant which makes the above expression a perfect square trinomial is 64
Humans took seeds from wild plants and grew them close to their homes, and the very early farmers observed that some plants had more favorable characteristics than others, such as better-tasting or more numerous or retained seeds, or were easier to grow, or were more vigorous.
