Question

find the roots of the following equation by facterisation x² – 3x – 10=0​

Answer 1

Step-by-step explanation:

x2+2x-5x-10=0

x (x+2)-5 (x+2)=0

(x+2)(x-5)=0

Answer 2

For the given equation

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

You should find the prime factors for 10 whose sum is -3. so show the possible prime factors are are 5 and 2. And for getting -3 we should we should take the larger number as negative and the smaller number as positive i.e., 5 should be negative and to must be positive. And then you can proceed easily.

Hope I helped you.
