Solution for 266=(18-x)(15+x) equation:


Simplifying
266 = (18 + -1x)(15 + x)

Multiply (18 + -1x) * (15 + x)
266 = (18(15 + x) + -1x * (15 + x))
266 = ((15 * 18 + x * 18) + -1x * (15 + x))
266 = ((270 + 18x) + -1x * (15 + x))
266 = (270 + 18x + (15 * -1x + x * -1x))
266 = (270 + 18x + (-15x + -1x2))

Combine like terms: 18x + -15x = 3x
266 = (270 + 3x + -1x2)

Solving
266 = 270 + 3x + -1x2

Solving for variable 'x'.
