Question

find the roots of the quadratic equation X square - 3 x-10 = 0 by factorization​

Answer 1

Answer:

x²-3x-10=0 ⇒ (x-5)(x+2)=0 ⇒ x-5=0   x+2=0 ⇒ x= 5,-2

Step-by-step explanation:

Answer 2

Hey friend,

Here is your answer :-

${x}^{2} - 3x - 10 = 0 \\ \\ {x}^{2} - 5x + 2x - 10 = 0 \\ \\ x(x - 5) + 2(x - 5) = 0 \\ \\ (x - 5) \: ( x + 2) = 0 \\ \\ x - 5 = 0 \\ x = 5 \\ \\ x + 2 = 0 \\ x = - 2$

Hence, the roots of this quadratic equation are 5 & -2

I hope this will help you....
