The sum of a and b will be the coefficient of the x term of the trinomial. This can be seen below.

(x + a)(x + b)
= x² + bx + ax + ab
= x² + (a+b)x + ab

x is being multiplied by both a and b individually and the products are being added, so sum of a and b appears as the coefficient of x term.

Thus the answer to this question is option C

4x+15=6x-5 solve for x

hram777 [196]

Answer:

x = 10

Step-by-step explanation:

Breaking down the equation

$4x+15=6x-5\\4x+15-15=6x-5-15\\4x=6x-20\\4x-6x=6x-20-6x\\-2x=-20\\\frac{-2x}{-2}=\frac{-20}{-2}$

Simplification

$\frac{-2x}{-2}\\=\frac{2x}{2} (\frac{-x}{-y} = \frac{x}{y})\\\frac{2}{2} = 1 = x\\\\\frac{-20}{-2}\\=\frac{20}{2}\\\frac{20}{2}\\=10$
