Question

Solve the following quadratic equation using the quadratic formula and then choose the correct solution set.

5x2 + 7x = 6

Answer 1

{ -2, 3/5 }

Explanation:

Answer 2

x = 3/5 or x = -2

Explanation:

For this equation: a=5, b=7, c=-6

5x^2 + 7x − 6 = 0

Step 1: Use quadratic formula with a=5, b=7, c=-6.

x= −b±√(b^2−4ac )/2a

x= −(7)±√(7)2−4(5)(−6) /2(5)

x=( −7±√169) /10

x= 3/5 or x= −2
