Answer:

(x + 7)² = 0

Step-by-step explanation:

Given

x² + 14x + 49 = 0 ( subtract 49 from both sides )

x² + 14x = - 49

To complete the square

add ( half the coefficient of the x- term)² to both sides

x² + 2(7)x + 49 = - 49 + 49

(x + 7)² = 0

Answer:

x=-2

Step-by-step explanation:

−5x−2+2x=−2x+4+2x

−3x−2=4

Step 2: Add 2 to both sides.

−3x−2+2=4+2

−3x=6

Step 3: Divide both sides by -3.

−3x

−3

Answer:

3 $a^{4}$ - 48

Step-by-step explanation:

Given

(a + 2)(3a² + 12)(a - 2)

= (a + 2)(a - 2)(3a² + 12) ← expand the first pair of parenthesis using FOIL

=(a² - 4)(3a² + 12) ← expand using FOIL

= 3 $a^{4}$ + 12a² - 12a² - 48 ← collect like terms

= 3 $a^{4}$ - 48
