Answer:
(2-6)(10) plus 3 to the power of 2, is <u>-31</u>.
Explanation:
Three to the power of two plus parenthesis two minus six parenthesis parenthesis ten. This is the same as the sum or addition of 3 times 3(3 times itself two times), and 2 minus 6 times 10.
This expression can be represented by (3^2) + (2-6)(10) which is (3 × 3) + (-4 × 10) which is 9 + -40 which simplifies to -31
4x² + 3x + 5 = 0
x = <u>-3 +/- √(3² - 4(4)(5))</u>
2(4)
x = <u>-3 +/- √(9 - 80)</u>
8
x = <u>-3 +/- √(-71)
</u> 8<u>
</u>x = <u>-3 +/- √(71 × (-1))</u>
8
x = <u>-3 +/- √(71) × √(-1)
</u> 8<u>
</u>x = <u>-3 +/- 8.43i
</u> 8
x = -0.375 +/- 1.05375i
x = -0.375 + 1.05375i x = -0.375 - 1.05375i
