Solve (-3x^2) + 4 = 0 by completing its square. !

The answer for (-3x^2) + 4 = 0 is x = 1.155 which is solved using simple algebra to find the x value from the equation. First, move 4 to the right side of the equal sign, thus we will see the -3x^2 = -4 equation, then, divide -4 by -3 so we can find the squared number of x resulting x^2 = 1.333. We can finish the problem by finding the square root number of 1.333 which is possible to be done because 1.333 is not an imaginary number.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

The correct answer is 10%
