When finding the zeros its 2 solutions can be found by applying the famous quadratic formula:
To solve 2x²+5x-3=0 using the Quadratic Formula we enter the coefficients a=2, b=5 and c=-3 into the above formula to get
Simplification yields
Since 25+24=49 we have
The Square Root of 49 is known to be 7
One solution is found by adding 7 , the second solution by subtracting 7
Simplifying both fractions finally yields the 2 real solutions
These two solutions can be verified by plugging them back into the given above Quadratic Equation.
