x^2+12x-64=0
⚠ 12x is read as the product 12*x: for a power, write 12^x
Let's solve in ℝ: x2 + 12x -64 = 0
You can transform this expression into: (x + 6)2 -100
(x + 6)2 -100 = 0
You can write the expression in factored form: ((x + 6) -10)·((x + 6) + 10)
Let's solve in ℝ: ((x + 6) -10)·((x + 6) + 10) = 0
ℹ6 -10 = -4‖6 + 10 = 16
(x -4)·(x + 16)
Let's solve in ℝ: x -4 = 0
Solution obtained: x = 4
Let's solve in ℝ: x + 16 = 0
Solution obtained: x = -16
▶Solution:   x = { -16, 4 }
