The two right sides of a right triangle are the roots of the equation x ^ 2-7x + 12 = 0, and the area of a right triangle is calculated~

The two right sides of a right triangle are the roots of the equation x ^ 2-7x + 12 = 0, and the area of a right triangle is calculated~

X ^ 2-7x + 12 = 0 (x-3) (x-4) = 0, x = 3 or x = 4, area = 3 * 4 / 2 = 6
