2. (x-4) (x-8)​

Sagot :

Answer:

1. (a+8)(a-5)

FOIL METHOD:

(a)(a) = a²

(a)(-5) = -5a

(8)(a) = 8a

(8)(-5) = -40

Solve like terms,

-5a + 8a = 3a

FINAL ANSWER = a² + 3a - 40

2. (x-4)(x-8)

FOIL METHOD

(x)(x) = x²

(x)(-8) = -8x

(-4)(x) = -4x

(-4)(-8) = 32

Solve like terms,

-8x - 4x = -12x

FINAL ANSWER: x² - 12x + 32

Answer:

[tex]1. (a + 8)(a - 5)[/tex]

[tex](a + 8) \times (a - 5)[/tex]

Multiply each term in the first parenthesis by each term in the second parenthesis (FOIL).

[tex]a \times a - 5a + 8a - 8 \times 5[/tex]

Calculate the product

[tex]a {}^{2} - 5a + 8a - 8 \times 5[/tex]

[tex]a {}^{2} - 5a + 8a - 40[/tex]

Answer:

[tex] = a {}^{2} + 3a - 40[/tex]

===========================================

[tex]2. (x - 4)(x - 8)[/tex]

[tex](x - 4) \times (x - 8)[/tex]

Multiply each term in the first parentheses by each term in the second parenthesis (FOIL).

[tex]x \times x - 8x - 4x - 4x( - 8)[/tex]

Calculate the product

[tex]x {}^{2} - 8x - 4x - 4x( - 8)[/tex]

[tex]x {}^{2} - 8x - 4x + 32[/tex]

Answer:

[tex] =x {}^{2} - 12x + 32[/tex]
