where is the figure

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
