Question

plz answer that one ☺☺☺☺​

Answer 1

Step-by-step explanation:

The roots are

${x}^{2} + 7x + 10 = 0 \\ {x}^{2} + 5x + 2x + 10 = 0 \\ (x + 2)(x + 5) = 0 \\ x = - 2 \: and \: x = - 5$

Verification:

Let the roots be alpha and beta.

From the polynomial, a=1, b=7 and c=10.

Now, alpha + beta=-b/a=-7/1=-7

Also, sum of roots=(-2)+(-5)=-7

Similarly, alpha × beta =c/a=10/1=10

Now, product of roots =(-2)(-5)=10

Hence verified

Thank you

Answer 2

Answer:

×^+7×+10

×^+2×+5×+10

×(×+2)+5 (×+2)

(×+2) (×+5)

×+2=0 ,×+5=0

×= -2 , ×= -5

This is your answer

I hope this helpful.
