(d)

This equation does not factor, but we can solve using the quadratic formula

x = ( - b ± √(b² - 4ac) )/ 2a

given the equation in standard form : ax² + bx + c = 0

divide through by - 1, to obtain

x² + 7x + 2 = 0

with a = 1, b = 7 and c = 2, then

x = ( - 7 ± √(49 - 8) ) / 2

  = ( - 7 ± √41 ) / 2

x = - ± √41 / 2 → (d)

answer: 25 is the correct answer
