Let's solve your equation step-by-step.<span><span><span><span>x2</span>−<span>10x</span></span>+18</span>=0

</span>Step 1: Use quadratic formula with a=1, b=-10, c=18.<span>x=<span><span><span>−b</span>±<span>√<span><span>b2</span>−<span><span>4a</span>c</span></span></span></span><span>2a

</span></span></span><span>x=<span><span><span>−<span>(<span>−10</span>)</span></span>±<span>√<span><span><span>(<span>−10</span>)</span>2</span>−<span><span>4<span>(1)</span></span><span>(18)</span></span></span></span></span><span>2<span>(1)

</span></span></span></span><span>x=<span><span>10±<span>√28</span></span>2

</span></span><span><span>x=<span>5+<span><span><span>√7</span><span> or </span></span>x</span></span></span>=<span>5−<span>√7
