Step 1
Quadratic Formula: For a quadratic equation ax2+bx+c=0, where a0,
the slutions are x=b±b24ac2a
Step 2
Given: x22.450x+1.500=0
Here, a=1, b=2.450 and c=1.500
Substitute these values in quadratic formula.
x=(2.450)±(2.450)24(1)(1.500)2(1)
=2.450±6.002562
Let us find the values of x using calculator.
x=2.450+0.00252=2.52=1.25
x=2.4500.00252=2.42=1.2
Rounding to three decimals, the solutions are x=1.200, x=1.250.
