Answer:
5cm
Step-by-step explanation:
it the correct answer
Ax² + bx + c = 0
2x² + x - 3 = 0
2x² + x + (-3) = 0
x = <u>-b +/- √b² - 4ac</u>
2a
x = <u>1 + /- √1² - 4(2)(-3)</u>
2(2)
x = <u>1 + /- √1 +24</u>
4
x = <u>1 +/- √25
</u> 4<u>
</u>x = <u>1 + /- 5
</u> 4<u>
</u>x = <u>1 + 5</u> x = <u>1 - 5
</u> 4 <u> </u> 4<u>
</u>x = <u>6</u> x = <u>-4</u>
4 4
x = <u>3</u> x = -1
2
x = 1 1/2
x = 1 1/2 x = -1
