Multiply: (–4x + 1)^2?

(-4x + 1)^2

Answer choice:

D. 16x^2 - 8x + 1

(-4x + 1)^2 = (-4x + 1)(-4x + 1)

Expand the brackets using the foil method:

16x^2 - 8x + 1

D. 16x^2 – 8x + 1

the answer is d. 16x^2 - 8x + 1

hope this helped!

another method using pascals triangle:

1

11

121 <----squared(we are going to use this)

1331<----cube

(-4x)^2 +(2)(-4x)(1) + (1)^2

=16x^2 -8x +1

through fact you comprehend common math, factoring, concept addition of user-friendly fractions. no want for extra clarification. in case you merely persist with heavily and understand the stairs decrease than, you will comprehend how its carried out: ((4x - 12) / (x^2 + 6x))(5x/(3 - x)) ((4x - 12) / (x^2 + 6x))(5x/(-x + 3)) (4((4x/4) - (12/4)) / (x^2 + 6x))(5x/(-x + 3)) (4(x - 3)) / (x^2 + 6x))(5x/(-x + 3)) (4(x - 3)) / x(x^2/x + 6x/x))(5x/(-x + 3)) (4(x - 3)) / x(x + 6))(5x/(-x + 3)) (4(x - 3))(5x) / (x(x + 6))(-x + 3) (4(x - 3)(5x)) / ((x)(x + 6)(-x + 3)) (4)(5)(x)(x - 3) / (x)(x + 6)(-x + 3)) CANCEL comparable words, NEGATE AS necessary: (4)(5)(x)(x - 3) / (x)(x + 6)(-x + 3)) (4)(5)(x)(-a million)(-x + 3) / (x)(x + 6)(-x + 3)) (4)(5)(-a million) / (x + 6) -20 / (x + 6) (3/x^7) / (6/x^3) (3/x^7) (x^3/6) 3x^3 / 6x^7 3x^3 / (2)(3x^7) a million / (2)(x^(7-3)) a million / (2)(x^4) a million / 2x^4 ((2x - 6)/21) / ((5x - 15)/12) ((2(2x/2 - 6/2))/21) / ((5x - 15)/12) ((2(x - 3))/21) / ((5x - 15)/12) ((2(x - 3))/21) / (5(5x/5 - 15/5)/12) ((2(x - 3))/21) / (5(x - 3)/12) ((2(x - 3))/21) (12/5(x - 3)) ((2(x - 3))(12) / (21)5(x - 3)) (2)(x - 3)(12) / (21)(5)(x - 3) (2)(12)(x - 3) / (21)(5)(x - 3) (2)(12) / (21)(5) (2)(2^2)(3) / (21)(5) (2)(2^2)(3) / (21)(5) (2^3)(3) / (21)(5) (2^3)(3) / (3)(7)(5) (2^3) / (7)(5) 8/35

(-4x+1)(-4x+1) then foil

16x^2-8x+1
