Question

What are the exact solutions of x2 = 4 − 7x?

x = x equals negative 7 plus or minus the square root of thirty-three all over 2

x = x equals negative 7 plus or minus the square root of sixty-five all over 2

x = x equals 7 plus or minus the square root of sixty-five all over 2

x = x equals 7 plus or minus the square root of thirty-three all over 2

Answer 1

x^2 + 7x - 4 = 0
x = [-7 +- sqrt(49 - 4* 1 * -4 ] / 2
= [ -7 +- sqrt(65)] / 2

second option is correct
