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

Both terms are squares:
is the square of
, while 25 is the square of 5. So, we can apply the factoring

To factor the expression as

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

2
The discriminant of the quadratic expression
is defined as

So, you have

3
Similarly, we have

Answer:
8
Step-by-step explanation:
2(2)^2‒3(2*‒3)‒2(‒3)^2
2*4‒3(‒6)‒2(9)
8‒(‒18)‒18
8+18‒18
26‒18
