Make sure you write all the terms on the left-hand side of the equation and simplify as much as possible before using the Quadratic Formula.
Roots: x= 5± isqrt(87)4 Number and Type of Roots: two imaginary roots
Practice makes perfect
We will use the Quadratic Formula to solve the given quadratic equation.
ax^2+ bx+ c=0
⇕
x=- b± sqrt(b^2-4 a c)/2 aWe first need to identify the values of a, b, and c.
2x^2-5x+14=0
⇕
2x^2+( - 5)x+ 14=0
We see that a= 2, b= - 5, and c= 14. Let's substitute these values into the Quadratic Formula. Remember that sqrt(- a)= isqrt(a).
