#### Answer:

or

#### Explanation:

Given:

#(m-7) = -(m-7)^2+3#

First add

#(m-7)^2+(m-7)-3 = 0#

This is in the form:

#ax^2+bx+c = 0#

with

So we can use the quadratic formula to find:

#m-7 = (-b+-sqrt(b^2-4ac))/(2a)#

#color(white)(m-7) = (-color(blue)(1)+-sqrt(color(blue)(1)^2-4(color(purple)(1))(color(brown)(-3))))/(2(color(purple)(1)))#

#color(white)(m-7) = (-1+-sqrt(1+12))/2#

#color(white)(m-7) = -1/2+-sqrt(13)/2#

Add

#m = 13/2+-sqrt(13)/2#
