A. 10x^2=3x+2
B. 2=3x+10x^2
C. 3x=10x^2-2
D. 10x^2+2=-3x

Answer 1

Answer:B

Answer 2

Answer: B. 2=3x+10x^2

Explanation:

The expression means the quadratic function equation.

B = 10x^2 + 3x -2 = 0

the equation is [-b ±√(b^2 -4ac)]/2a

b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.
