Webb1 maj 2024 · Evaluate 2x2 + 3x + 8 when x = 4. Solution We need to be careful when an expression has a variable with an exponent. In this expression, 2x2 means 2 • x • x and is different from the expression (2x)2, which means 2x • 2x. exercise 2.3.11 Evaluate: 3x2 + 4x + 1 when x = 3. Answer exercise 2.3.12 Evaluate: 6x2 − 4x − 7 when x = 2. Answer Webb2x 2 - 2x + 5x - 5 Step-4 : Add up the first 2 terms, pulling out like factors : 2x • (x-1) Add up the last 2 terms, pulling out common factors : 5 • (x-1) Step-5 : Add up the four terms of step 4 : (2x+5) • (x-1) Which is the desired factorization. Canceling Out : 6.3 Cancel out (2x+5) which appears on both sides of the fraction line.

WebbSimplify 3 x + 2 ( x – 4) Solution In this case, it is impossible to combine terms when they are still in parentheses or any grouping sign. Therefore, eliminate the parenthesis by multiplying any factor outside the grouping by all terms inside it. Hence, 3 x + 2 ( x – 4) = 3 x + 2 x – 8 = 5 x – 8 WebbSimplify the following: (2x + 3y + 4z)(4x 2 + 9y 2 + 16z 2 - 6xy - 12yz - 8zx) Study Material. Mathematics.
