Answer 2

Step-by-step explanation:

→5x'=4x+7

→5x'-4x-7=0.

→ Here, a=5;. b=-4; c=-7;

→ x= -b±√b'-4ac eq 1

2a

→ Substitute the values in the equation 1

→ x= -(-4)±√(-4)'-4(5)(-7)

2(5)

→ x= 4±√16+140

10

→ x= 4±√156

10

→ x= 4±2√39

10

→ x= 4+2√39 or x= 4-2√39

10 10

→ x=2(2+1√39) x= 2(2-1√39)

10 10

→ x= 2+1√39 x= 2-1√39
