We can solve this problem using discriminant.
x^2-4x-12's discriminant is
(-4)^2-4*-12=16+48 which is clearly larger than 0
This means that it crosses over the axes 2 times.
In case you don't know what discriminant is, its in equation ax^2+bx+c
the discriminant is b^2-4ac.
If its positive it has 2 crosses with x axis, if negative then 0 crosses, if 0 then 1 cross.
Hope this helped at least a little bit :D

Step-by-step explanation:
Step-by-step explanation:
a/q first we have to find the measurement of third side
so,
h² = a² + b²
4² = a² + 2²
16 = a² + 4
a = 16 - 4 = 12
a² = 12
a = √12 = 3.46
so,
area of square = a × a
= 3.46 × 3.46 = 11.97 sq unit
