For the answer to the question above, I'll provide my solutions below. x² + 4 = 0 <span> - 4 - 4 </span> x² = -4 x = +2i x² - 6x + 1 = 0 x = -(-6) +/- √((-6)² - 4(1)(1)) 2(1) x = 6 +/- √(36 - 4) 2 x = <span>6 +/- √(32) </span> 2 x = <span>6 +/- 2√(2) </span> 2 x = 3 + √(2) x = 3 + √(2) x = 3 - √(2) I hope this helps.
