Detailed Solution & Explanation

Given the quadratic equation:
x27x+10=0x^2 - 7x + 10 = 0
We can factor the quadratic equation by splitting the middle term:
x25x2x+10=0x^2 - 5x - 2x + 10 = 0
x(x5)2(x5)=0x(x - 5) - 2(x - 5) = 0
(x2)(x5)=0(x - 2)(x - 5) = 0
Solving for x\displaystyle x:
x2=0    x=2x - 2 = 0 \implies x = 2
x5=0    x=5x - 5 = 0 \implies x = 5
Thus, the roots of the equation are 2\displaystyle 2 and 5\displaystyle 5, which matches Option a.
**Option a**
