Step-by-step explanation:
(e) (x-8)(x-9)
Multiplying two binomials.
x(x-9)-8(x-9)
x² -9x - 8x + 72
x² - 17x + 72
(f) 6x⁴ - 12x
Common factoring.
6x(x³ - 2)
(g) x² + 8x + 12
Factoring trinomial of the form ax² + bx + c.
x² +2x + 6x + 12
x(x + 2) + 6(x + 2)
(x + 2) (x + 6)
(h) (x + 7)(x + 5)
Multiplying two binomials.
x(x + 5)+7(x + 5)
x² + 5x + 7x + 35
x² + 12x + 35
(i) x² - 36
Difference of two squares.
a² - b² = (a + b)(a - b)
x² - 6²
a = x, b = 6
(x + 6)(x - 6)
Ответ:
e) x^2-17x+72 multiply two binomials
f) 6x(x^3-2) common factoring
g) (x+6)(x+2) factor a trinomial
h) x^2+12x+35 multiply two binomials
i) (x+6)(x-6) difference of squares
Step-by-step explanation:
e)
(x-8)(x-9)
=x(x-9)-8(x-9)
=x^2-9x-8x+72
=x^2-17x+72 multiply two binomials
f)
6x^4-12x
= 6(x^4 - 2x)
= 6x(x^3-2) common factoring
g)
x^2+8x+12
= x^2+2x +6x+12
= x(x+2) + 6(x+2)
= (x+6)(x+2) factor a trinomial
h)
(x+7)(x+5)
=x^2+5x + 7x +35
= x^2+12x+35 multiply two binomials
i)
x^2 - 36
= (x+6)(x-6) difference of squares
