The answer is A) -5 (if you get the app math papa you can plug in the equation and plug in the values to get the answer.)
times both sides by 2x
x(x+2)=2(4)
x²+2x=8
minus 8 both sides
x²+2x-8=0
factor
what 2 numbers multiply to -8 and add to 2
-2 and 4
(x-2)(x+4)=0
set to zero
x-2=0
x=2
x+4=0
x=-4
x=-4 and 2
The prime factors of the polynomial 24x4 – 3x are 3x, 2x -1 and (4x2 + 2x + 1)
<h3>Prime factorization</h3>
Given the polynomial function expressed as:
24x^4 – 3x
Factorize
y = 24x^4 – 3x
Factor out the GCF
y = 3x(8x^3 - 1)
Factor the expression in parenthesis
y = 3x((2x)^3 - 1^3)
y = 3x(2x-1)((2x)^2 + 1^2 +2x)
y = 3x(2x -1)(4x^2 +2x + 1)
Hence the prime factors of the polynomial 24x4 – 3x are 3x, 2x -1 and (4x2 + 2x + 1)

If she studied for 2.3 she would have a total of 11.5 because if she got 5 points per hour you just have to multiply it the number of hours she spent studying. So 2.3 x 5 = 11.5! :-)
wqual because you round 0.6 to 1 and 0.4 to 0 so 2+1 is 3
