Question

What should be subtracted from ×2 +13×+7to get 3×square +5×-4 ​

Answer 1

Step-by-step explanation:

Let

the polynomial which should be subtracted=P

• According to question

${:}\longrightarrow$${x}^{2}+13x+7={3x}^{2}+5x-4+P$

${:}\longrightarrow$$P={x}^{2}+13x+7-({3x}^{2}+5x-4)$

${:}\longrightarrow$$P={x}^{2}+13x+7-{3x}^{2}-5x+4$

${:}\longrightarrow$$P={x}^{2}-{3x }^{2}+13x-5x+7+4$

${:}\longrightarrow$${\underline{\boxed{\bf {P=(-{2x}^{2}+8x+11)}}}}$
