Add the following
(5x²+3 x-8) , (4 x+7-2 x²) and(6-5 x+4 x²
Answers
Answer:
7+2x+5
Explanation:
(5+3x-8)+(4x+7-2)+(6-5x+4) Original equation
(5+3x-8)+(-2+4x+7)+(4-5x+6) Rearrange the equation to make
the solving process simpler.
5+3x-8-2+4x+7+4-5x+6 Remove parentheses. (Before each
set of parentheses is a 1, which was
unnecessary to include.) After
distributing the 1, each equation
stays the same.
7+2x+5 Simplify. I highlighted each group in
a specific way. I bolded the
coefficients with , italicized the
coefficients with x, and underlined
the numbers without an x beside
them. These groupings help you
add/subtract the numbers. You can
only add 5 with -2 and +4
because they are like terms. same
for the terms with only x and the
numbers without an x. When you
finish adding and subtracting the like
terms your answer will be 7+2x+5.
