Question Simplify the expression x2−3 Evaluate x2−1×2−1Multiply the numbers x2−2−1Solution x2−3 Show Solution Find the roots x1=−3,x2=3Alternative Form x1≈−1.732051,x2≈1.732051 Evaluate x2−1×2−1To find the roots of the expression,set the expression equal to 0 x2−1×2−1=0Any expression multiplied by 1 remains the same x2−2−1=0Subtract the numbers x2−3=0Move the constant to the right-hand side and change its sign x2=0+3Removing 0 doesn't change the value,so remove it from the expression x2=3Take the root of both sides of the equation and remember to use both positive and negative roots x=±3Separate the equation into 2 possible cases x=3x=−3Solution x1=−3,x2=3Alternative Form x1≈−1.732051,x2≈1.732051 Show Solution
