The answer is S ( that's what I got when I put it into a graphing calculator)
The square root of 25 is an irrational, real number.
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

D
there is always a 1 infront of a variable but since x2 has the largest degree it gives it priority over the others so what ever numbe in front of it is the leading coefficient
