Answer 2

Answer:

x2-3x-10=0

Step-by-step explanation:

x2-3x=10______(1)

Third term=(1/2×coefficient of middle term)square

=(1/2×3)2

=(3/2)2

= 9/4

add 9/4 on both side of equation (1)

(1)=

x2+3x+9/4=10+9/4

(x+3/2)2 = 31/4

(x+3/2)2 = (√31/2)2

x+3/2=√31/2. or. x+3/2= -√31/2

x=√31/2-3/2. or. x= -√31/2-3/2

x=√31-2/2. or. x=-√31-3/2.
