Question

a. ax+ay
b.
$16 {x}^{2} + 2 {ay}^{2}$
c.
${ax}^{3} + {bx}^{2} - cx$
d. 2x-2+yx-y

e.
$2 {a}^{2} - 4 {b}^{2}$
f.
$25 {x}^{2} - 1$
g.
${x}^{2} + 6x + 9$
h.
${x}^{2} - 6x + 64$

Answer 1

A. ax+ay = a(x + y)

b.

16 {x}^{2} + 2 {ay}^{2}

16x² + 2ay²

2(8x² + ay²)

c.

{ax}^{3} + {bx}^{2} - cx

ax³ + bx² - cx

x(ax² + bx - c)

d. 2x-2+yx-y

2x - 2 + yx - y

2(x - 1) + y(x - 1)

(x - 1)(2 + y)

e.

2

{a}^{2} - 4 {b}^{2}

2a² - 4b²

2(a² - 2b²)

f.

25 {x}^{2} - 1

25x² - 1 = (5x + 1)(5x - 1)

g.

{x}^{2} + 6x + 9

x² + 6x + 9 = (x + 3)(x + 3)= (x + 3)²

h.

{x}^{2} - 6x + 64

x² - 6x + 64 = ????
