Question

factorizar 4x² +12x - xy - 3y​

Answer 1

Respuesta:

Explicación paso a paso:

4x²–y 4x²–y

x³–8 (x-2)(x² + 4x + 4)

r²–16 (r–4)(r + 4) =

2x² + 13x + 6 (2x)² + 13(2x) + 12 = (2x + 12)(2x + 1) /2•1 = (x + 6)(2x + 1)

49 – 14x + x² (7 – x)²

4x² + 12x – xy – 3y (4x²–xy) + (12x–3y) = x(4x –y) –3(4x– y)  = (x–3)(4x–y)

64x^6 – 8y^3 (4x²–2y)(16x³ + 8x²y + 4y²)

24x⁴y – 96x³y² + 48x² __ 24x²(xy – 4xy² + 2)

x² – 8x –7 x²–8x–7

2a²–2a +ab – b __ (2a²–2a) + (ab–b) = 2a(a–1) + b(a–1) = (2a + b)(a–1)

2x² + 4x – 48 (2x)² + 4(2x) –96 = (2x + 12)(2x–8)/2= (x + 6)(x - 4)
