Solve the quadratic by factorizing x2+ 2x-8

x = -4 & +2

Step-by-step explanation:

equation: x^2 + 2x -8 = 0

=> x^2 + 4x - 2x -8 = 0 (*4x-2x= 2x)

=> x(x + 4) -2( x + 4) = 0 (taking out the common factor)

=> ( x + 4) ( x - 2 ) = 0

Case I

=> ( x + 4 ) = 0

=> x = -4

Case II

=> ( x - 2 ) = 0

=> x = 2

Therefore, x = -4 and +2

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
