Answer 2

Answer:

Given equation: $x^{2} -3x-10=0$

The two roots that we get on solving this equation are -2 and 5.

Step-by-step explanation:

Given equation :

$x^{2} -3x-10=0$

This is an quadratic equation and at first we need to factorise the equation

We need to find 3 from the factor of 10, and we need to subtract the factors of 10 to get 3 because the sign before 10 is -.

Factors of 10 are 2,5: 5-2=3

$x^{2} -5x+2x-10=0\\x(x-5)+2(x-5)=0\\(x+2)(x-5)=0$

Which means that either (x+2)=0 or (x-5)=0

The roots of the quadratic equation are -2 and 5.
