12-4x+24x^2=0
⚠ 4x is read as the product 4*x: for a power, write 4^x
⚠ 24x is read as the product 24*x: for a power, write 24^x
Let's solve in ℝ: 12 -4x + 24x2 = 0
You can write the expression in factored form: 4·(3 -x + 6x2) = 0
Let's solve: 3 -x + 6x2 = 0
Given the quadratic form ax2 + bx + c, you can calculate the discriminant: Δ = b2 -4ac
Δ = (-1)2 -4·6·3
ℹ(-1)2 = 1‖4·6 = 24
Δ = 1 -24·3
Δ = 1 -72
Δ = -71
Since Δ < 0, the equation has no solution.
