Question

Write the degree of 3 Find the value of 7x-6x2+2 at X=-2

Answer 1

Answer:

$a= \frac{6x^{2}-7x-2 }{2tx}$

$t=\frac{6x^2-7x-2}{2ax}$

Step-by-step explanation:

Let's solve for a.

7x−6x2+2atx=−2

Step 1: Add 6x^2 to both sides.

2atx−6x2+7x+6x2=−2+6x2

2atx+7x=6x2−2

Step 2: Add -7x to both sides.

2atx+7x+−7x=6x2−2+−7x

2atx=6x2−7x−2

Step 3: Divide both sides by 2tx.

$\frac{2atx}{2tx} =\frac{6x^2-7x-2}{2tx}$

Let's solve for t.

7x−6x2+2atx=−2

Step 1: Add 6x^2 to both sides.

2atx−6x2+7x+6x2=−2+6x2

2atx+7x=6x2−2

Step 2: Add -7x to both sides.

2atx+7x+−7x=6x2−2+−7x

2atx=6x2−7x−2

Step 3: Divide both sides by 2ax

$\frac{2atx}{ax} =\frac{6x^2-7x-2}{2ax}$
