Question

2 X square + 27 X + 90 is equals to zero solve by completing square​

Answer 1

Step-by-step explanation:

2x^2 + 27x + 90 = 0

Factoring the equation,

2x^2 + 12x + 15x + 90 = 0

2x(x+6) + 15(x+6) = 0

(2x+15)(x+6)=0

Applying zero product rule,

x = -6

x = -7.5

Hence the roots of the equation are -6 and -7.5
