It is known that 2-radical 3 is a solution of the equation x squared-4x + a = 0. Find another root of the equation and the value of A
According to Weida's theorem, if the sum of two roots is 4, then the other root is 2 + root 3, and the product of two roots is a, then a = 2-root 3 times 2 + root 3 = 1
2.9x-1.4x = 60
2.9x-1.4x=60
1.5x=60
15x=600
x=40
Solving equation 9x + 15 = 4x-2
9x-4x=-2-15
5x=-17
x=-17/5
