Answer: 5
Step-by-step explanation: Let's go over a little algebra terminology.
The number in front of your variable is called your coefficient and a variable is just a letter that represents any number.
So here, your coefficient is 5 since it appears in front of the variable, x.

it would be answer a
Step-by-step explanation:
that's all i have
293 is a prime number, so you can't divide it in factors
Answer:
{-2,10}
Step-by-step explanation:
x^2 - 8x = 20
Take the coefficient of x
-8
Divide by 2
-8/2 =-4
Square it
(-4)^2 =16
Add this to each side
x^2 - 8x+16 = 20+16
x^2 - 8x+16 = 36
The left hand side becomes( x + (-8/2) )^2
(x - 4)^2 = 36
Take the square root of each side
sqrt((x - 4)^2) =±sqrt( 36)
x-4 = ±6
Add 4 to each side
x-4+4 = 4±6
x = 4±6
x = 4+6 x = 4-6
x = 10 x = -2
