\left(x-3\right)^{2}+\left(x-3\right)\left(5x-2\right)
Multiply x-3 and x-3 to get \left(x-3\right)^{2}.
x^{2}-6x+9+\left(x-3\right)\left(5x-2\right)
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(x-3\right)^{2}.
x^{2}-6x+9+5x^{2}-2x-15x+6
Apply the distributive property by multiplying each term of x-3 by each term of 5x-2.
