Question

solve the quadratic equation x²+25x-3150=0​

Answer 1

Here is your solution :-

${x}^{2} + 25x - 3150 = 0 \\ {x}^{2} + 70x - 45x - 3150 = 0 \\ x(x + 70) - 45(x + 70) = 0 \\ when \: (x + 70) = 0 \\ x = - 70 \\ when \: (x - 45) = 0 \\ x = 45$

Answer 2

Answer:

Step-by-step explanation:

Formula=-b+_√b^2-4ac/2a

A=1

B=25

V=-3150

= -25+_√625-4×1×-3150/2×1

= -25+_√625-(-12600)/2

= -25+_√625+12600/2

= -25+_√13225/2

= -25+_115/2

= x=-25+115/2 or x=-25-115/2

= x= 90/2 or x= -140/2

= x= 45 or x= -70
