Practice problem
Simplify the expression by combining like terms:
−3x2+x2+7x+1−17-3x^2 + x^2 + 7x + 1 -17−3x2+x2+7x+1−17
−2x2+7x−18-2x^2 + 7x - 18−2x2+7x−18
−3x2+7x−16-3x^2 + 7x - 16−3x2+7x−16
−2x2+7x−16-2x^2 + 7x - 16−2x2+7x−16
−4x2+7x−16-4x^2 + 7x - 16−4x2+7x−16
Type a concept, like “slope” or “photosynthesis”.
