4x²-3x²74x-5
solve​

Answer 1

Step-by-step explanation:

${3x}^{2}-{4x}^{2}+5x+{x}^{2}+2x-3x+4+4x {}^{2}-{3x}^{2}+74x-5$

• First combine like polynomials

${:}\longmapsto$ ${3x}^{2}-{3x}^{2}-{4x}^{2}+{4x}^{2}+{x}^{2}+5x+2x-3x+4x+74x+4-5$

• Now simplify

${:}\longmapsto$ $0+0+{x}^{2}+7x-7x+74x-1$

${:}\longmapsto$${x}^{2}+74x-1$
