Answer: 7
Step-by-step explanation:
-5 x -1 - (-2).
First, -5 x -1 = two negatives make a positive, so 5.
Now, 5 - (-2), two negatives signs make a positive sign, so 5 + 2.
Now, 5 + 2 = 7.
4x² + 23x = -28
4x² + 23x + 28 = 0 move all terms to one side.
4x² + 16x + 7x + 28 = 0 split the second term into two terms
4x(x + 4) + 7(x + 4) = 0 factor.
(x + 4)(4x + 7) = 0 factor.
x = -4, -7/4
hope this helps, God bless!
I'd like to look at this as both a math joke and a warm message.
Thank you, love.
