For this question you should first add -4d on both sides of the equation and then add +16 on both sides:
25d - 4d = 26+16
21d = 42
d = 42/21
d = 2 :)))
I hope this is helpful
have a nice day
Answer:
x = 7, x = -3
Step-by-step explanation:
We can find the zeros by factoring the equation using the zero product property.
x^2-4x-21 = 0
(x-7)(x+3) = 0
<u>x-7 = 0</u>
x = 7
<u>x+3 = 0</u>
x = -3
Zeros are x=7 and x= -3.
