Find the discriminant of 3x^2 - 10x = -2.

For any quadratic equation:      ....[1]

then;

the discriminant is given by:

Given the equation:

we can rewrite this equation as:

On comparing the given equation with equation [1]  we have;

a = 3 , b = -10 and c = 2

then;

or

therefore, the discriminant of is 76

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

i think that you should ask google for the answer to that problem because if we don't know it google does
