Question

Given that a = -1, b=2 and c= -3 ,find the value of a(b2+c2)

Answer 1

a(
`b^(2)`+
`c^(2)`) = = -13

Explanation:

Given that a = -1, b=2 and c= -3

find the value of a(
`b^(2)`+
`c^(2)`)

Just substitute the values given for each variable

a(
`b^(2)`+
`c^(2)`) = (-1)(
`2^(2)`+
`(-3)^(2)`) ; do the exponents first

a(
`b^(2)`+
`c^(2)`) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;

a(
`b^(2)`+
`c^(2)`) = -13 ; and multiply by -1
