(-5m^2-8) -(-3m^2+m+2)=(−5m 2 −8)−(−3m 2 +m+2)

m = 2 or m = 0

Step-by-step explanation:

Solve for m over the real numbers:

(-5 m^2 - 8) - (-3 m^2 + m + 2) = (-5 2 m - 8) - (m - 3 2 m + 2)

(-5 m^2 - 8) - (-3 m^2 + m + 2) = -2 m^2 - m - 10 and (-5 m 2 - 8) - (m - 3 m 2 + 2) = -5 m - 10:

-2 m^2 - m - 10 = -5 m - 10

Add 5 m + 10 to both sides:

4 m - 2 m^2 = 0

Factor m and constant terms from the left hand side:

-2 m (m - 2) = 0

Divide both sides by -2:

m (m - 2) = 0

Split into two equations:

m - 2 = 0 or m = 0

Add 2 to both sides:

m = 2 or m = 0

m = 0, 2.

Step-by-step explanation:

(-5m^2-8) -(-3m^2+m+2)=(−5m *2 −8)−(−3m* 2 +m+2)

= -5m^2 - 8 + 3m^2 - m - 2 =  -10m - 8 + 6m - m - 2

= -2m^2 + 4m = 0

2m( -m + 2) = 0

m = 0,  2.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

the answer is simply just 6n add the two together as they have an n
