Solve each of the following equations using a method other than the Quadratic Formula.
liraira [26]

Answer:

A)

y^2-6y = 0

or, y(y-6) = 0

or, y = 0 or y = 6

B)

n^2+5n+7 = 7

or, n^2+5n+7-7 = 7-7 ( Subtracting 7 from both sides)

or, n^2+5n = 0

or, n(n+5) = 0

or, n=0 or n= -5

C)

2t^2-14t+3 = 3

or, 2t^2-14t = 0

or, 2t(t-7) = 0

or, t=0 or t=7

D)

1/3x^2+3x-4 = -4

or, 1/3x^2+3x = 0

or, 1/3x(x+9) = 0

or, x=0 or x= -9

E)

Zero is a common solution to each of the equations. This is because each of the equations had a variable outside the parenthesis with an operation of multiplication.

Hassan and Dionnie played a game of darts, and Dionnie scored 4 more points than Hassan. The total of their scores was 180. How
Varvara68 [4.7K]

Answer:

Let Hassan score be X

Then Dionnie score will be  X + 4

: the sum of Hassan and Dionnie is 180

X + ( X + 4 ) = 180

X + X + 4 = 180

COLLECTING LIKE TERMS

2X = 180 – 4

2X = 176

DIVIDING EACH TERM BY 2

2X/2 = 176/2

X = 88

: Hassan scored 88 and Dionnie score 92
