-3x+12x−12=0

what's the discriminate

0

Step-by-step explanation:

discriminant = b^2 - 4ac

12^2 - 4 × (-3)×(-12) ➡ 144 - 144 = 0

0

Step-by-step explanation:

-3x²+12x−12=0

discriminant D,

= b² - 4ac

= 12² - 4(-3)(-12)

= 144 - 4(3)(12)

= 144 - 144

= 0

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

because they could drop even lower..
