Explanation Given Information: The provided quadratic equation is 2 x 2 − 5 = 0 . Formula used: The value of x in the equation a x 2 + b x + c = 0 can be given by the quadratic formula, x = − b ± b 2 − 4 a c 2 a where a , b and c are real numbers with a ≠ 0 . Calculation: Consider the quadratic equation 2 x 2 − 5 = 0 . Compare the above equation with the equation a x 2 + b x + c = 0 , a = 2 , b = 0 and c = − 5 Put the values of a , b , c in the quadratic formula x = − b ± b 2 − 4 a c 2 a . x = − 0 ± ( 0 ) 2 − 4 ⋅ 2 ( − 5 ) 2 ⋅ 2 = 0 ± 40 4 = 0 ± 2 10 4 = ± 5 2 Further simplify, x = 5 2 Or x = − 5 2 Check: For x = 5 2 Substitute the value of x = 5 2 in 2 x 2 − 5 = 0
