Question

find the value of x (5x+4) (8x-71)

Answer 1

Answer:

x = -4/5 or x = 71/8

Step-by-step explanation:

Solve for x:

(5 x + 4) (8 x - 71) = 0

Split into two equations:

5 x + 4 = 0 or 8 x - 71 = 0

Subtract 4 from both sides:

5 x = -4 or 8 x - 71 = 0

Divide both sides by 5:

x = -4/5 or 8 x - 71 = 0

Add 71 to both sides:

x = -4/5 or 8 x = 71

Divide both sides by 8:

Answer:  x = -4/5 or x = 71/8

Answer 2

Answer:

−11360

are factor (−1)×2

5

×5×71

Step-by-step explanation: for -11360

(5×+4)(8×−71)

Multiply 5 and 4 to get 20.

20×8(−71)

Multiply 20 and 8 to get 160.

160(−71)

Multiply 160 and −71 to get −11360.
