Use the square root property to determine all real solutions for each of the following equations.

`2u^2-36 = 0`

 ` u= `  

`5b^2+135 = 0`

` b= `  

Give exact solutions (don't use decimals), and separate multiple solutions with commas. If there are no real solutions, type DNE.

Box 1: Enter your answer as a list of values separated by commas: Example: -4, 3, 2
Enter each value as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 2^3, 5+4)
Enter DNE for Does Not Exist, oo for Infinity
Decimal values are not allowed
