Find the product of (x − 5)2. X2 10x 25 x2 − 10x 25 x2 − 25 x2 25.

Serggg [28]

Answer:

x^2 -10x+25

Step-by-step explanation:

(x − 5)^2

(x-5)(x-5)

FOIL

first x*x = x^2

Outer -5 *x = -5x

inner -5*x = -5x

last -5*-5 =25

Add them together x^2 -5x-5x+25

Combine like terms x^2 -10x+25

Solve for x: x^2 + 28x = 60

Alisiya [41]

For this case we have a quadratic equation, $x ^ 2 + 28x-60 = 0$ , of the form $ax ^ 2 + bx + c = 0$

Where:

$a = 1\\b = 28\\c = -60$

We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.

These numbers are:

$+30\ and\ -2\\+ 30-2 = + 28\\+ 30 * -2 + -60$

Then, the factorization is given by:

$(x-2) (x + 30) = 0$

The roots are:

$x_ {1} = 2\\x_ {2} = - 30$

Answer:

$x_ {1} = 2\\x_ {2} = - 30$
