6 squared is 36. 36 plus 3 is 39
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
6 squared plus 9 squared is equal to 117.
9 - 4 =5, 5+36= 41
104
2^2 + 3^2 = 4 + 9 = 13
(5x + 2)(x + 3)
That factors to (2c + 3)(3c + 2)
(x + 3)(x + 2)
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
