X2 + X = 15
X2 + X - 15 = 0
Looks like a job for the quadratic formula. ( the discriminant says two real roots )
X = - b (+/-) sqrt(b2- 4ac)/2a
a = 1
b = 1
c = - 15
X = - 1 (+/-) sqrt[12 - 4(1)(- 15)]/2(1)
X = - 1 (+/-) sqrt(1 + 60)/2
X =[ - 1 (+/-) sqrt(61)]/2
---------------------------------exact answer
So, X = ~ 3.41
X = ~ - 4.41

IF 2 plus 3 equals 10. 7 plus 2 equals 63. 6 plus 5 equals 66. 8 plus 4 equals 96 therefore 9 plus 7 equals?
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.
