Incorrect. Because there is the exponent 2 on the outside of the parentheses, you must multiply the coefficient by itself: $\displaystyle{\left(-\frac{{2}}{{5}}\right)}\cdot{\left(-\frac{{2}}{{5}}\right)}\usepackage{cmbright}\Huge\$ . Remember that you must also multiply the exponents within the parentheses by the exponent on the outside of the parentheses.
