Solve:
25x%5E2%2B16+=+0 Subtract 16 from both sides.
25x%5E2+=+-16 Take the square root of both sides.
5x+=+sqrt%28-16%29 But sqrt%28-16%29+=+sqrt%2816%2A%28-1%29%29=4%2Asqrt%28-1%29
5x+=+4%2Asqrt%28-1%29 Substitute sqrt%28-1%29+=+i
5x+=+4%2Ai Divide both sides by 5.
highlight%28x+=+%284%2F5%29i%29
