Answer:
Option B
Step-by-step explanation:
Given quadratic equation is,
y = 2x² + 5x - 7
By comparing this equation with y = ax² + bx + c
a = 2, b = 5 and c = -7
Solution of the polynomial (2x² + 5x - 7) can be determined by the quadratic formula,
Substitute the values of a, b and c.
Therefore, Option B will be answer.
