Answer:
(x - 5i)(x + 5i)
Step-by-step explanation:
Write this as x^2 + 25. Solving for x^2, we get x^2 = -25.
Recall that the square root of a negative number is an imaginary one. √(-25) equals ±5i (there are two roots, one positive and one negative).
Then x = ±5i.
In factored form, the given expression is (x - 5i)(x + 5i).

Answer:
Brady will have earned $75 in interest.
Step-by-step explanation:
The interest formula is i = p*r*t, where p is the principal amount, r is the interest rate as a decimal fraction, and t is the number of years.
Here, i = $600(0.025)(5 yr) = $75.
Brady will have earned $75 in interest.
