x^2+10x=18
round to the nearest hundreth
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
