WebMay 1, 2024 · Answer. Example 2.3.6: evaluate. 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. 2x2 + 3x + 8. Substitute 4 for each x. 2(4)2 + 3(4) + 8.

Webx2+2x+2 Final result : x2 + 2x + 2 Step by step solution : Step 1 :Trying to factor by splitting the middle term 1.1 Factoring x2+2x+2 The first term is, x2 its coefficient is 1 . The ... WebThe triangle can be used to calculate the coefficients of the expansion of (a + b)n by taking the exponent n and adding 1. The coefficients will correspond with line n + 1 of the triangle. For (2x - 3y)7, n = 7 so the coefficients of the expansion will correspond with line 8. WebThe other two forms are standard y=ax^2+bx+c and factored form y=(ax+b)(cx+d). These are the three forms of quadratics. The idea of a^2x^2 + 2abx + b^2 is just a special case of the standard form which happens to be simple to get into factored form (ax+b)^2. Same with difference of perfect squares where a^2 x^2 - b^2 factors to (ax+b)(ax-b). jennifer maldonado gomez
