Question

solve the equation by using formulae method
2x² + 13x + 15 = 0​

Answer 1

Step-by-step explanation:

compare the given equation with standard form ax²+bx+c=0

therefore, a=2, b=13, c=15

∆=b²-4ac

=(13²)-4(2)(15)

=169-120

=49

x= -b+/-√b²-4ac/2a

x= -13+7/4 OR x= -13-7/4

x= -3/2 OR x= -5

Therefore, x= -3/2 OR x=-5
