Q. Find the Roots of the quadratic equation x2−3x−10=0 using Factorization method
Write Quadratic Equation: Write down the quadratic equation that needs to be solved.The given quadratic equation is x2−3x−10=0.
Factorize Equation: Factorize the quadratic equation.To factorize x2−3x−10=0, we need to find two numbers that multiply to −10 and add up to −3.
Find Factorization Numbers: Find the two numbers that satisfy the conditions for factorization.The numbers −5 and 2 multiply to −10 and add up to −3. Therefore, we can write the quadratic equation as (x−5)(x+2)=0.
Set Equations Equal: Set each factor equal to zero and solve for x. Setting each factor equal to zero gives us two equations: x−5=0 and x+2=0.
Solve First Equation: Solve the first equation x−5=0. Adding 5 to both sides of the equation x−5=0 gives us x=5.
Solve Second Equation: Solve the second equation x+2=0.Subtracting 2 from both sides of the equation x+2=0 gives us x=−2.
Write Roots: Write down the roots of the quadratic equation.The roots of the equation x2−3x−10=0 are x=5 and x=−2.
