We have been given that [tex]m=6x+5[/tex]. We are asked to rewrite the equation [tex](6x+5)^2-10=-18x-15[/tex] in terms of m.
First of all, we need manipulate right side of our given equation.
We will factor out -3 from right side of equation as:
[tex](6x+5)^2-10=-3(6x+5)[/tex]
Upon substituting [tex]m=6x+5[/tex] in our equation, we will get:
[tex](m)^2-10=-3(m)[/tex]
[tex]m^2-10=-3m[/tex]
Upon writing this equation in general form of equation, we will get:
[tex]m^2+3m-10=-3m+3m[/tex]
[tex]m^2+3m-10=0[/tex]
Therefore, the equation [tex]m^2+3m-10=0[/tex] is equivalent to our given equation.
