X = 1 means that one of the factors is (X – 1) and
X = –7 means that the other factor is (X + 7)
Multiply them together (X – 1)(X + 7) and the equations is X2 + 6X – 7 = 0

x²+x - 6
Step-by-step explanation:
Let α= 2 and β=-3
So, Sum of zeros= α+β => 2+(-3)=> 2-3=> -1
Product of zeros= αβ => 2×-3 => -6
Standard form of quadratic equation = x²-(α+β)x + αβ
= x²-(-1)x+(-6)
= x²+1x-6
= x²+x - 6
