Question

Evaluate the expression when m= -6
m²+5m-1​

Answer 1

`\huge\boxed{\bf\:5}`

Explanation:

Expression =
`m^(2) + 5m - 1`.

They've given the value of m as - 6.

Then, by substituting - 6 in place of 'm' in the equation,

`m^(2) + 5m - 1\\= (-6)^(2) + 5(-6) - 1\\= 36 - 30 - 1\\= \boxed{\bf\:5}`

`\rule{150pt}{2pt}`

Answer 2

When m = -6, then we have:

m² + 5m - 4

Explanation:

(-6)² + 5 x (-6) - 4

36 - 30 + 4

36 - 34
