Evaluate 7x - (2x)2 + x 3 for x = -2.

V125BC [204]

$7x - (2x)2 + {x}^{3}$

$7x - 4x + {x}^{3}$

$3x + {x}^{3}$

$3( - 2) + { (- 2)}^{3}$

$- 6 + - 8$

$- 14$

What the 2 soultion answer to <br> y = 6x − 4<br> y = 5x − 3

d1i1m1o1n [39]

$y= 6x -4~~~~~~...(i)\\\\y = 5x -3~~~~~~...(ii)\\\\\text{From (i) and (ii):}\\\\~~~~~6x -4 = 5x -3\\\\\implies 6x -5x = -3 + 4\\\\\implies x = 1\\\\\text{Substitute x = 1 in equation (i):}\\\\y = 6(1) -4 = 2\\\\\text{Hence,}~ (x,y) = (1,2)$

What is the third term in the binomial expansion of (3x + y3)4?

Serggg [28]

Answer:

$18x^2y^6$ that is option third is correct

Explanation:

We have been given with the expression $(3x+y^3)^4$

We have general formula for binomial expansion which is

$a^n +na^{n-1}b+ \frac{(n)(n-1)}{2} a^{n-2}b^2+----------+b^n$

Here $a= 3x , b=y^3and\\n=4$

Substituting the values in the formula we will get

$3x^4+4(3x)^{4-1}y^3+ \frac{(4)(4-1)}{2} 3x^{4-2} (y^{3})^2\\\\ (3x)^4+4(3x)^3y^3+6(3x)^2y^6\\\\(3x)^4+12x^3y^3+18x^2y^6$ +----

we can clearly see that third term of the expansion will be

$18x^2y^6$

Therefore, Option third is correct
