3² + 20 ÷ 2² = 9 + (20 ÷ 4) = 14.
4 plus (4 squared) = 8
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
x2 + 9x + 20 = 0 ∴(x + 4)(x + 5) = 0 ∴x ∈ {-5, -4}
6x2+23x+20=0x= .7275 and -4.5634Improved Answer:-6x2+23x+20 = (3x+4)(2x+5) when factored
3² + 20 ÷ 2² = 9 + (20 ÷ 4) = 14.

2 squared plus 2 squared equals 16 because 2 squared is 4 times 4 equals 16. Math: 4x4=16 so your answer is 16 :)!
4, -5

Assuming the thing is as written and there are no brackets missed out then it is just 4 squared times 3 = 16x3=48.
x2 + 9x + 20 = 0 ∴(x + 4)(x + 5) = 0 ∴x ∈ {-5, -4}
6x2+23x+20=0x= .7275 and -4.5634Improved Answer:-6x2+23x+20 = (3x+4)(2x+5) when factored
1 squared plus 8 squared or 4 squared plus 7 squared
(x + 5) (x - 4)
4 squared plus 4 squared divided by 4 plus 4
