Solve for x using the Master Product.<br> 4x^2 + 8x + 3 = 0<br> Master Product:<br> And try

<h2>quadratic equation</h2>

the solution of the quadratic equation is twofold, to find the solution, you can factor it first.

4x² + 8x + 3 = 0

4x² + 6x + 2x + 3 = 0

2x(2x + 3) + 1(2x + 3) = 0

(2x + 3) (2x+1) = 0

2x+3=0 or 2x+1=0

x=-3/2 x=-1/2

<em><u>You can try to prove that the x value above will produce 0</u></em>

• first x = -3/2

= 4(-3/2)² + 8(-3/2) + 3

= 9 - 12 + 3

= 0 (true ✔️)

• second x = -1/2

= 4(-1/2)² + 8(-1/2) + 3

= 1 - 4 + 3

= 0 (true ✔️)

Two lines intersect to form four angles. The measure of one angle is 27 degrees. Draw a diagram to show the measures of the othe

Snowcat [4.5K]

Since there is a 180 degrees in a straight line and we know that the intersection of one angle is 27 degrees we can can say 180 -27 = 153 degrees. So the four angles would be 27, 27 153, 153
