Question

plz tell me the answer​

Answer 1

a²+10a+24

=a²+6a+4a+24

=a(a+6)+4(a+6)

=(a+6)(a+4)

Answer 2

Answer:

a²+10a+24

by quadratic formula

discriminant(d)=b²-4ac

so here a=1

b=10

c=24

put all the values in discriminant

d= (10)²- 4x1x24

100-96

=4

now quadratic formula= b±√d/2a

put value of d in quadratic formula

we get,

10±√4/2x1

alpha=10+√4/2x1

10+2/2

12/2=6

beta=10-√4/2x1

10-2/2=8/2

=4
