Question

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

Answer 1

Answer:

a($b^{2}$+$c^{2}$) = = -13

Step-by-step 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
