Question

Apply the distributive property (assume all variables are non zero):

k²(1−10/k²⁾

 

please help me 

Answer 1

k squared (1-10/k squared) In order to apply the distributive property, multiply each term inside the parentheses by the term outside the parentheses. The variable cannot be 0 because division by 0 (0 in the denominator) is undefined. k2(1-10/k2) = k2(1) - k2(10/k2) = k2 - 10(k2/k2) The k2 terms in the numerator and denominator cancel out because any number divided by itself equals 1. Therefore, the expressions simplifies to: = k2 -10 read as k squared - 10
