11. Find the solutions of x^2-x-30 = 0. Please give a walkthrough/step by step I am trying to learn how to do it!

To find the solutions of quadratic equation, there are two ways to do which are:

Step 1

- Factor the expression.

To factor the expression, refer below:

For bx and ax, both can be common-factored. Therefore

From the above, we conclude that:

From the expression, 30 comes from 5×6 and when 5-6 = -1. Therefore, a can be 5 and b can be 6.

Because in the middle term, it is -x which is negative, we have to let the highest number become negative.

From the factored expression:

Then we replace the standard equation with factored form.

For this part, we solve like a linear equation where we isolate x. Just think you are solving two linear equations!

Hence

Therefore, the solutions are x = -5, 6.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
