Question

x²+2x=143 find the value of x?
step by step anwer it.......
​

Answer 1

Answer:

• x = -13 and 11

Step-by-step explanation:

• x² + 2x - 143 = 0
• x² + 13x - 11x - 143 = 0
• x(x + 13) -11(x + 13) = 0
• (x + 13) (x - 11)
• x = -13 and x = 11

Hence, the value of X is - 13 and 11

Answer 2

x^2 + 2x = 143

Step-by-step explanation:

x^2 + 2x - 143 = 0

x^2 + 13x - 11x - 143 =0

x ( x + 13 ) - 11 ( x + 13 ) = 0

( x -11 ) (x+13) = 0

x = 11 & -13
