How do you multiply #(5 + x)(3 - 2x)#?

Answer 1

Isaiah Anthony

#=color(blue)(2x^2 - 7x +15#

#color(blue)((5+x))(3−2x)#

#=color(blue)((5)) * (3)+color(blue)((5)) * (-2x) + color(blue)(x) *(3) + color(blue)(x) .(-2x)#

#=15-10x +3x-2x^2#

#=color(blue)(2x^2 - 7x +15#

To multiply (5 + x)(3 - 2x), you use the distributive property, multiplying each term in the first expression by each term in the second expression, and then combining like terms. This simplifies to 15 - 10x + 3x - 2x^2, which further simplifies to -2x^2 - 7x + 15.
