18x24 6x22 5Solution18x24 6x22 5 we use PEDMAS first we

18x²+4 - [ 6(x²-2) +5]

Solution

18x²+4 - [ 6(x²-2) +5]

we use PEDMAS

first we have to perform operation inside Parentheses \"( )\"

after that we go for exponents (power and squareroots)

then Divison and multiplication from left to right

last we gor for Addition and subtraction from left to right

we follow this rule to solve our problem

18x²+4 - [ 6(x²-2) +5]

first we will operate inside Parentheses

18x^2 + 4 - [ 6x² - 12 + 5]          we have distributed \"6\" over the bracket (x^2 - 2) . so we multiply 6 inside the bracket terms

18x^2 + 4 - [ 6x² - 7 ]    // -12 +5 = -7

18x² + 4 - 6x² + 7   // whenever there is a negative sign before a bracket we reverse the sign of the terms inside the bracket.

12x² + 11
