Identify Quadratic Expression: To "rise" an expression typically means to factor it, which is to rewrite the expression as a product of its factors. The given expression is a quadratic expression, so we will look for two binomials that multiply to give the original expression. The expression is 2x2+7x+6.
Find Factors: First, we need to find two numbers that multiply to give the product of the coefficient of x2 (which is 2) and the constant term (which is 6), and add up to the coefficient of x (which is 7). The two numbers that satisfy these conditions are 2 and 3, since 2×3=6 and 2+3=5, which is not 7. We made a mistake here; we need to find another pair of numbers.
