Answer:
Additive = -10x^2+70x
Multiplicative = 1/10x(x−7)
Step-by-step explanation:
The multiplicative inverse of a number is the reciprocal of that number. Since 10(x^2−7x)⋅ 1/10x(x−7)=1 , then 1/10x(x−7) is the multiplicative inverse of 10(x^2−7x) .
Since 10(x^2−7x)−10x^2+70x=0 , then −10x^2+70x
is the additive inverse of 10(x^2−7x).
