Question

[(3x-5y)²+(x-4y)(x+4y)-(3y)²]÷(-5x)

Answer 1

x^2+10x-4y-33=0; 8x^2+5y^2−4xy+8*sqrt(5)x+16sqrt(5)y+64=0. Identical expressions (3x–4y)^ two – five (x+ two y– one)^2= one . (3x–4y) squared –5(x plus 2y–1) squared equally 1. (3x–4y) to the power of two – five (x plus two y– one) squared equally one . (3x–4y)2–5(x+2y–1)2=1. (3x–4y)²–5(x+2y–1)²=1.
