B and C
Step-by-step explanation:
First, we need to get the left side equal to zero. Take away 25 from each side to get .
We can use the quadratic equation of to find the solutions.
Plug them in to get .
Simplify.
or
1 and -4
x = 1 and -4
It is already rounded to the nearest hundreth. .5 is a tenth, .06 is a hundreth.
(2a-7)(a+4)
2a(a) + 2a(4) + (-7)(a) + (-7)(4)
2a^2 + 8a -7a - 28
Combine like terms
2a^2 + a -28
