A3

B2

C-2

D-3

Answer:

D. -3

Read Explanation:

p(x)=2x2+4x6p(x) = 2x ^ 2 + 4x - 6

p(3)=2(32)+4(3)6p(-3)=2(-3^2)+4(-3)-6

The product of the roots of 3x² - 13x + 6 = 0 is:
Simplify 3(3x2)+x(4x2)+1512.3(3x - 2) + x(\frac{4x}{2})+15-12.

If 1+31 + \sqrt{3} and 131 - \sqrt{3} are the roots of a quadratic equation, then the quadratic equation is:
