What is the missing constant term in the perfect square that starts with X^2 - 8x
xenn [34]

Answer:

16

Step-by-step explanation:

Perfect square in the quadratic from ax² + bx + c

You know an equation is perfect when:

2√(ax²)√(c) = bx

Substitute x² for ax² and 8x for bx. Then isolate c by doing the reverse operations.

2√(ax²)√(c) = bx

2√(x²)√(c) = 8x

2x√c = 8x   Divide both sides by 2x

√c = 4    Square both sides to isolate c.

c = 16

The missing constant term is 16.

Check answer:

x² - 8x + 16

(x - 4)²

= (x - 4)(x - 4)

= x² - 4x - 4x + 16

= x² - 8x + 16
