x^2+10x=18

Question

round to the nearest hundreth

Answer 1

To solve for x, we need to rearrange the equation and use the quadratic formula:

First, we can move the constant term to the other side:

x^2 + 10x - 18 = 0

Then we can use the quadratic formula:

x = (-10 ± sqrt(10^2 - 4(1)(-18))) / 2(1)

x = (-10 ± sqrt(136)) / 2

x ≈ -9.29 or x ≈ -0.71

Rounding to the nearest hundredth:

x ≈ -9.29 or x ≈ -0.71
