Question

Write in standard form (×+4)(×-5)=4 find the value of a,b,c​

Answer 1

`x^(2)` - x - 24 = 0

a = 1

b = 1

c = -24

Explanation:

(x + 4)(x - 5) = 4

x(x - 5) =
`x^(2)` - 5x

4(x - 5) = 4x - 20

`x^(2)` - 5x + 4x - 20 = 4

`x^(2)` - x - 20 = 4

`x^(2)` - x - 20 - 4 = 0

`x^(2)` - x - 24 = 0

a = 1

b = 1

c = -24
