Which value is needed to create a perfect square trinomial from the expression x2 + 8x + _____?

1 answer:

4 0

I believe it's +16, if you complete the square you'd have (x+4)^2 - 16 + a = 0 where a is the value you're looking for, so to make this correct you need a = 16

1) m - 38 = -44 * m = --6 o m = 6 m = 82 O m = --82

galina1969 [7]

$m-38=-44$

$+38$ $+38$ add 38 on both sides, solve for -44 + 38 which is -6.

__________

$m = -6$ , is your final answer.

Remember
$x^{-m}= \frac{1}{x^m}$

so

$10^{-4}= \frac{1}{10^4}= \frac{1}{10000}=0.0001$
