9. Find the roots of the equation x2+7x+10=0
Answers
Answer:
-5 and -2
Step-by-step explanation:
Given a quadratic equation
x^2 + 7x + 10 = 0
To find the roots of the equation
We need to factorise the equation.
Therefore, we will get,
=> x^2 + 5x + 2x + 10 = 0
Taking common terms,
=> x(x+5) +2(x+5) = 0
=> (x+5)(x+2) = 0
Solving further, we will get,
=> x+5 = 0
=> x= -5
And
=> x+2 = 0
=> x = -2
Hence, roots are -5 and -2.
