Answer:
Step-by-step explanation:
The values of a and b from the quadratic equation 2x2 - 5x + 7 = 0 are - 0.1419 and + 2.6419. These answers are explained step -wise below :
- A quadratic equation is defined as an equation which on standard form can be rearranged as ax2 + bx + c = 0;
where x represent unknown number and a, b , c are the known numbers where a is not equal to zero but if its equals to zero then equation becomes linear.
- The given quadratic equation is:
2x²+5x-7 = 0
so, here the values of a, b and c are
a= 2 ;
b= -5 ;
and c= 7
