If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
'20 squared' simply means 20 multiplied by itself (20 x 20). This equals 400.
The solutions are: x = 4, y = 2 and x = -4, y = -2
Simple. When a number is 'squared' it simply means it is multiplied by itself. So, '20 squared' means 20 x 20, which equals 400.
36. 4 squared is 16...16 + 20 - = 36.
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
4, -5
2 squared plus 2 squared equals 16 because 2 squared is 4 times 4 equals 16. Math: 4x4=16 so your answer is 16 :)!
It can not be factored because its discriminant is less than zero
20 = 400

'20 squared' simply means 20 multiplied by itself (20 x 20). This equals 400.
The solutions are: x = 4, y = 2 and x = -4, y = -2
7/20 + 3/9 = 41/60
Simple. When a number is 'squared' it simply means it is multiplied by itself. So, '20 squared' means 20 x 20, which equals 400.
x2 - 9x + 20 = (x - 4)( x - 5)
36. 4 squared is 16...16 + 20 - = 36.
