Question

How to factor d^2+10d+9

Answer 1

you have to find the solutions to d^2 +10d + 9 = 0

Answer 2

d^2+9d+d+9
d(d+9)+1(d+9)
(d+9)(d+1)
i guess its enough there is no need to put it equal to 0 as u r asking to factorize not to find the roots

Answer 3

your solution is more simple, but i'm afraid it must me hard sometimes (but i gess it's enough for tayler).

Answer 4

you could use the formula:
d1 = [-10+sqrt(10^2 - 4*9)]/2
d1 = (-10+sqrt64)/2
d1 = (-10+8)/2
d1 = -1
d2 = (-10-8)/2
d2 = -9

Answer 5

Then, knowing the solutions of the equation, d1 and d2, you can factorize:
(d - d1)(d - d2) = (d + 1)(d + 9)
