Solve for x to 3dp: x^2 + 6x + 2 = 0
We cannot factorise this so we shall use the quadratic formula instead.We need to substitute in the values for a, b, and c.ax2 + bx + c = 0x2 + 6x + 2 = 0a = 1, b=6, c=2Once substituted in, we get 2 values (remember we must do both the ± versions)Final Answers:x = -0.354 & x = -5.646 Both to 3dp
