Answer:
10.4
Explanation:
to simply solve the expression we will insert the known value of x into the expression and evaluate.
12-2x^2/-5x
12 - 2x²/-5x given that x = -4
= 12 - 2 (-4)²/ -5(-4)
= 12 - 2(16)/ 20
= 12 -32/20
don't forget to the BODMAS rule
B...................... bracket
O................. of
D..........................................division
M................................ multiplication
A................................ addition
S.................................. subtraction
so we have,
12 - 32/20
12 - 8/5
find the lcm
60 - 8/5
52/5
10.4
