Simplify −(−6a^3 + 0.2a^2 − 7) Thank you for helping me with this one :)
−(−6a^3+0.2a^2−7)
[-(-6a)=6a]
[-(-7)=7]
−(−6a^3+0.2a^2−7)=6a^3-0.2a^2+7=
[6a^3=6a^2*a]
−(−6a^3+0.2a^2−7)=6a^3-0.2a^2+7=6a^2*a-0.2a+7=
a^2(6a-0.2)+7
−(−6a^3+0.2a^2−7) =(6a-0.2)a^2 + 7
−(−6a^3+0.2a^2−7)
[-(-6a)=6a]
[-(-7)=7]
−(−6a^3+0.2a^2−7)=6a^3-0.2a^2+7
[6a^3=6a^2*a]
−(−6a^3+0.2a^2−7)=6a^3-0.2a^2+7=6a^2*a-0.2a^2+7= a^2(6a-0.2)+7
−(−6a^3+0.2a^2−7) =(6a-0.2)a^2 + 7
To simplify the expression −(−6a^3 + 0.2a^2 − 7), we can apply the distributive property by multiplying each term inside the parentheses by -1. This will change the signs of each term.
So, we have:
−(−6a^3 + 0.2a^2 − 7) = (-1)(-6a^3) + (-1)(0.2a^2) + (-1)(-7)
Simplifying further:
= 6a^3 - 0.2a^2 + 7
Therefore, the simplified expression is 6a^3 - 0.2a^2 + 7.
