Answer 1

Respuesta:

$a) x^{2} +2(x)(4)+4^{2} => x^{2} +8x+16\\b) x^{2} +2(x)(7)-7^{2} => x^{2} +14x+49\\c) 4x^{2} -5y^{2} =>16x-25y\\d) n^{3}+3(n)^{2}4+3n(4)^{2} +4^{3} => x^{3} +36n^{2} +48n+64\\e) a^{3} +3(a)^{2} 2b+3a(2b)^{2} +2b^{3}=> a^{3} +6ab^{2}+12ab+8b\\f) x^{2} +2y^{2} +2z^{2} +2(x)(2y)+2(2y)(2z)+2(x)(2z)=>x^{2} +2y^{2} +2z^{2} +4xy+8yz+4xz\\g) x^{2} +(5+7)x+(5)(2)=> x^{2} +12x+10$
