Answer 1

Explicación paso a paso:

1.

a) P = (x + 4)(x + 6) =>

${x}^{2} + 10x + 24$

b) C = (x - 5)(x - 8) =>

${x}^{2} - 13x + 40$

c) M = (x + 3)(x - 12) =>

${x}^{2} - 9x - 36$

d) Q = (x + 11)(x - 4) =>

${x}^{2} + 7x - 44$

2. Q = (4x - 6)(4x + 1) =>

${16x}^{2} - 5x - 6$

No hay respuesta.

3. S = (x + 7) - ( +10)(x + 4) =>

$(x + 7) {}^{2} - {x}^{2} - 14x - 40$

${x}^{2} + 49 - {x}^{2} - 14x - 40$

$- 14x + 9$

4.

$(x + y) {}^{2} = {12}^{2}$

${x}^{2} + 2xy + {y}^{2} = 144$

${x}^{2} + 2(7) + {y}^{2} = 144$

${x}^{2} + 14 + {y}^{2} = 144$

${x}^{2} + {y}^{2} = 130$
