Question

द्विघात सूत्र का प्रयोग कर समीकरन x^2+12+ 35 = 0 का हल निकाले।​

Answer 1

-5,-7

Step-by-step explanation:

=x ^ 2 + 12x + 35 = 0

=a * x ^ 2 + bx + c = 0

formula=x = (- b plus/minus sqrt(b ^ 2 - 9ac))/(2a)

a = 1 、 b = 12, c = 35

=x = (- b plus/minus sqrt(b ^ 2 - 4ac))/(2a)

= -12±√(12) 2-4×1×35/2

-12 ± √√√144 - 190/2

−12+2/2

x = -12+2/2

= -10/2

= -5

x = -12-1/2

-14/2

= -7

x= -5,-7
