Answer:

(x - 3)(x + 10)

Step-by-step explanation:

Break the expression into groups :

(x^2 -3x) + (10x - 30)

Factor out x from x^2 - 3x

=  x (x - 3)

Factor out 10 from 10x - 30

=  10 (x - 3)

=  x (x - 3) + 10 (x - 3)

(x - 3)(x + 10)

Express y=-2x^2-5x-18 as y=a(x-p)(x-q), where a,h, and k are constants. Hence state the equation of the line of symmetry and hen
UkoKoshka [18]

Answer:

y = -2·x^2 - 5·x - 18

y = -2·(x^2 + 10·x + 36)

y = -2·(x^2 + 10·x + 36)

y = -2·(x - (-5 - √11·i))·(x - (-5 + √11·i))

Maybe there is a typo in the original question, because there is no factorisation in the real numbers.

Because the question is " find the minimum value of y" the coefficient before x^2 must be a positive number. so it could be

y = 2·x^2 - 5·x - 18

Mark jogged 0.6 mile caroline jogged 0.49 mile write an inequality to compare the distances they jogged
horsena [70]
Hi there!

Since 0.6 is more than 0.49,

0.6 > 0.49

would be the inequality.

Hope this helps!
