find the difference between (-7)^{2 }and -(7)^{2}

Difference between (-7)^{2} and -(7)^{2}

Rules of algebra to remember – Square of every number (negative or positive) is always positive.

Negative sign multiplied to a positive number makes the number negative

SOLUTION

(-7)^{2} = -7×-7 = 49

and

-(7)^{2} = -(7×7) = -49

Difference between (-7)^{2} and -(7)^{2 }= 49 - (-49) = 49 + 49 = 98

If we take it otherwise, difference between -(7)^{2} and (-7)^{2 }= -49 - 49 = -98

These are the two possibilities as mentioned above.
