Question

2n²+34n=0 , solve by factorisation method​

Answer 1

Answer:

38n

bcause 2n*2n=4n

so 4n +34n=38n

Answer 2

Answer:

COMMON FACTOR :

2n² + 34n = 0

2(n² + 17n) = 0

DIVIDE BOTH SIDES OF THE EQUATION BY THE SAME TERM

2(n² + 17n) = 0

n² + 17n = 0

USE THE QUADRATIC FORMULA

n =

$- b \: + - \sqrt{b { }^{2 - 4ac} } \div 2a$

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

n² + 17n = 0

a = 1

b = 17

c = 0

$n \: = \: - 17 + - \sqrt{17 {}^{2} - 4 \times 1 \times 0 } \div 2 \times 1$

n = 0

n = 17
