There is a square and a triangle
the area of a square is
A = b * h
A = 2*2
A = 4

the area of the triangle is
A = (b*h)/2
A = (2 *2)/2
A = 4/2
A = 2

Now we add them up to find the total area
4 + 2 = 6
The shape has an area of 6 units^2

Move everything to the left by subtracting 25 from both sides:

$81x^2-25=0$

Both terms are squares: $81x^2$ is the square of $9x$ , while 25 is the square of 5. So, we can apply the factoring

$a^2-b^2=(a+b)(a-b)$

To factor the expression as

$(9x+5)(9x-5)=0$

A multiplication is zero if and only if one of the factors is zero, so we have

$(9x+5)(9x-5)=0 \iff 9x+5=0 \lor 9x-5=0 \iff x=-\dfrac{5}{9} \lor x=\dfrac{5}{9}$

The discriminant of the quadratic expression $ax^2+bx+c$ is defined as

$\Delta = b^2-4ac$

So, you have

$\Delta = 0^2-4\cdot(-1)\cdot(-25) = -100$

Similarly, we have

$\Delta = 7^2-4\cdot(-3)\cdot 6 = 49+72=121$
