Question

AYÚDENME PORFAVOR !!?!? PLISSSS heuekwjeh

Answer 1

Recuerda que:

$(a+b)^{2} =a^{2} +2ab+b^{2}$

Usando esta fórmula, resolvemos los incisos:

1)(x-8)²

$(x-8)^{2} =\\\\(x)^{2} +2(x)(-8)+(-8)^{2} =\\\\x^{2} -16x+64$

2)(2x-6)²

$(2x-6)^{2} =\\\\(2x)^{2} +2(2x)(-6)+(-6)^{2} =\\\\4x^{2} -24x+36$

3)(8x³-4)²

$(8x^{3}-4 )^{2} =\\\\(8x^{3} )^{2} +2(8x^{3} )(-4)+(-4)^{2} =\\\\64x^{6} -64x^{3} +16$

4)(7+x)²

$(7+x)^{2} =\\\\(7)^{2} +2(7)(x)+(x)^{2} =\\\\49 +14x+x^{2}$

5)(a+b)²

$(a+b)^{2} =\\\\a^{2} +2ab+b^{2}$

6)(5m-10x)²

$(5m-10x)^{2} =\\\\(5m)^{2} +2(5m)(-10x)+(-10x)^{2} =\\\\25m^{2} -100mx+100x^{2}$
