Brief Exaplanation: Step 1: Combine like terms First, identify and group the like terms in the expression -2×2+8x−9+4x+7×2+2: 2 terms: – 22 and +72 terms: +8x and +4x Constant terms: -9 and +2 Next, combine the coefficients for each group: For 2: -2+7 = 5, resulting in 5×2. For : 8+4 = 12, resulting in 12. For constants: -9+2 = 7. Step 2: Form the […]
