Ineed to factor and solve each quadratic equation.
x²-3-4=0

x²-7 = 0   part 1 and part 2 :  x = sqrt(7) or x = -sqrt(7)

Step-by-step explanation:

Solve for x:

x^2 - 7 = 0

Add 7 to both sides:

x^2 = 7

Take the square root of both sides:

 x = sqrt(7) or x = -sqrt(7)

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.
