Question

For the polynomial x2 + 10x + 25, a = b = .

Answer 1

Answer:

a and b there is no a and b but x would = 7.5

Step-by-step explanation:

Answer 2

Answer:

The values are a=1 b=10 c=25 and solving the expression we get x=-5

Explanation:

Given equation; $x^{2}+10 x+25$

Solution:

The above equation can be written as $x^{2}+10 x+25=0$

This equation is in the form of $A x^{2}+B x+C=0$

$A x^{2}+B x+C=0$ is the general quadratic equation.

Comparing the above equation we get  

A=1, B=10 and C=25

To find value of “x” we use the formula as  

=$\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Substitute the values of a, b and c in the above equation we get

=$\frac{-(10) \pm \sqrt{10^{2}-4(1)(25)}}{2(1)}$

=$\frac{-(10) \pm \sqrt{100-4(1)(25)}}{2}$

=$\frac{-(10) \pm \sqrt{100-100}}{2}$

=$\frac{-10}{2}$

=-5

Results:

Thus the values are A=1, B=10, C=25 and X=-5
