Values needed to complete the X diagram are:
On top -28, On the bottom: -3 and On the sides: -7 and 4.
<h3>What do you mean by
factorization?</h3>
An algebraic expression is factorised when it is written as the product of its factors.
The given equation is :
F(x) = x²-3x-28
finding factors,
= x²-7x+4x-28
= x(x-7) +4(x-7)
= (x-7)(x+4)
Given general equation is ax²+bx+c,
on comparing with x²-3x-28
a = 1
b = -3
c = -28
ac = 1*(-28) = -28

Answer:
can I have options? or is there not any?
Hi!
I'm quite sure the answer should be 24.
Two numbers that multiply to -2 could be
-1 and 2
Or
-2 and 1.
Since -1+2=1, -1 and 2 are the numbers you are looking for.
Hope this helps!
