Answer:
x=5 ; Area= 84m²
Step-by-step explanation:
(x+2)²+(4x+2)²=(5x)²
x²+4+4x+16x²+16+32x=25x²
8x²-36x-20x=0
x=5;x=-1
hypotenuse should be positive
x=5
area=lxb/2
Answer: (x + 3)(x - 4)
Step-by-Step Solution:
We need to Factorize the given Quadratic Polynomial by using Splitting the Middle Term Method.
= x^2 - x - 12
= x^2 - 4x + 3x - 12
= x(x - 4) + 3(x - 4)
=> (x + 3)(x - 4)
