15,000 to the third power that equals pi plus 12 would make it the square root of 7
2x2 equals 5
3
2x2
2x2 + 11x + 15 = (x + 3)(2x + 5).
8 - 2x2 = x + 22 - 7Combine like terms on the right side:8 - 2x2 = x + 15Subtract 8 from each side:-2x2 = x + 7Add 2x2 to each side:0 = 2x2 + x + 7
-7
If 2x2 + 3x + 9 = 0 then x = -0.75 - 1.984i or -0.75 + 1.984i where i is the imaginary square root of -1.
x2 + x2 = 2x2
No.
22 = 4
If: 2x2 = 4 Then: x = the square root of 2
