Two numbers are 10 units away in different directions from their midpoint, m, on a number line. The product of the numbers is –9

Gnesinka [82]

Answer:

$m {}^{2} - 100 = - 99$

Step-by-step explanation:

Set up the binomial.

$(m - 10)$

$(m + 10)$

Multiply the binomial.

$(m - 10)(m + 10) = - 99$

Apply difference of squares rule

$(p + q)(p - q) = p {}^{2} - q {}^{2}$

$m {}^{2} - 100 = - 99$
