Let a and b be the solutions to x^2 + x − 3 = 0. Find the value of a^3 − 4b^2 + 19. If you can't solve it don't answer.
This is a challenge.
Good luck!

0.037

Step-by-step explanation:

Given that,

Let a and b be the solutions to

It can be solved using quadratic formula where a = 1, b = 1 and c = -3

So,

Let a = 1.3, b = -2.3

The value of can be given by :

So, the value of the given expression is 0.037.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
