Is the polynomial prime? <br> 7x2-35x+2x-10

wolverine [178]

The given polynomial is not a prime polynomial.

Given the polynomials, we have to choose the polynomial which is prime.

A polynomial with integer coefficients that cannot be factored into lower degree polynomials is Prime polynomials.

$7x^2-35x+2x-10$

$7x^2-33x-10$

$\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}$

<h3>What is the formula for the quadratic roots?</h3>

$\quad x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$\mathrm{For\:}\quad a=7,\:b=-33,\:c=-10$

$x_{1,\:2}=\frac{-\left(-33\right)\pm \sqrt{\left(-33\right)^2-4\cdot \:7\left(-10\right)}}{2\cdot \:7}$

$x_{1,\:2}=\frac{-\left(-33\right)\pm \:37}{2\cdot \:7}$

$x_1=\frac{-\left(-33\right)+37}{2\cdot \:7},\:x_2=\frac{-\left(-33\right)-37}{2\cdot \:7}$

$x=5,\:x=-\frac{2}{7}$

Therefore the factor is (x-5) and (7x+2).

can be factored

∴ not a prime polynomial.

8(x+1)-7x ≥-3 help me find the solution

Ann [662]

Answer:

x $\geq$ 11

Step-by-step explanation:

$8\left(x+1\right)-7x$

$8x+8-7x$

$x+8$

Then..

$x+8\ge \:-3$

Subtract 8 from both sides

$x+8-8\ge \:-3-8$

Then, you got your awnser.

$x\ge \:-11$
