if:
y = x2
y = x + 6
then
x2 = x + 6
=> x2 - x - 6 =0
=> (x - 3)(x + 2) = 0
=> x = 3 or -2
=> y = 9 or 4 respectively, ie the points (3, 9) and (-2, 4).

Two solutions and they are:- x = 0 and y = 3
To calculate 6 squared plus 8 squared, you first need to square each number individually. 6 squared is 6 x 6, which equals 36. 8 squared is 8 x 8, which equals 64. Adding these two results together, you get 36 + 64, which equals 100. So, 6 squared plus 8 squared is 100.

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.
The solutions to the quadratic equation are: x = -1 and x = 6
(-4,-6)
b = sqrt32 or 4 root 2
X squared = x+6 6+x=x squared X=6
This is the common form of the Pythagorean Theorem. It describes the relationship between the two legs of a right triangle and the hypotenuse.
